Abstract: A blow-by gas filtration assembly fluidically connects to a crankcase ventilation circuit of an internal combustion engine. The filtration assembly has an axis and includes a filter group having a hollow cylindrical shape with a central chamber radially traversable by the blow-by gases, preferably from the outside to the inside. In addition, the filtration assembly includes a support and control member engageable to the filter group for supporting it in an axial position along the axis and for controlling it in rotation around the axis to perform the filtration operations. The member and the filter group include, respectively, a threaded member portion and a threaded filter portion engageable by reciprocal screwing. The member and the filter group also include, respectively, a member abutment and a filter abutment axially engageable along the axis to prevent further screwing of the threaded member portion and a threaded filter portion.

Abstract: An oil temperature regulator assembly fluidly connects to both an oil circulation system and a cooling system of an operating group of a vehicle. The oil temperature regulator assembly includes a beat exchanger including an upper exchanger plate, intermediate exchanger plates, and a lower exchanger plate. The stacking of the plates defines an oil flow zone and a cooling fluid flow zone including, planar oil flow regions and planar fluid flow regions alternating with each other along the vertical axis and including, respectively, vertical oil ducts and vertical fluid ducts fluidly connected to respective planar flow regions. The oil temperature regulator assembly includes a base device engaged to the lower exchanger plate. The upper exchanger plate or base device includes an operating opening vertically aligned with a vertical oil duct. The oil temperature regulator assembly includes a filtering cartridge insertable through an operating opening in the vertical oil duct.

Abstract: A filter cartridge is for a vehicle fluid filter group that includes a filter body and cartridge engagement members in the filter cartridge and body engagement members in the filter body. The cartridge engagement members and body engagement members are configurable by mutual axial movement between an engagement configuration and a disengagement configuration. The cartridge filter includes an end plate with the cartridge engagement members arranged around the cartridge axis. The cartridge engagement members include two blocking groups, each blocking group including a blocking element. Each blocking element includes a stem and a tooth laterally projecting from the stem and defining an engagement undercut. In the blocking configuration, the tooth is in a housing region of the body engagement members, and an engagement projection is housed in the undercut. In axial movements, each stem yields elastically radially and/or laterally upon action of the engagement projection on the tooth.

Abstract: A vehicle air filtration assembly includes a box having a longitudinal axis and a wall extending along first and second axes. A filter cartridge includes tubular filter media operatively connected to a plate group. The plate group has a first face with a sealing profile and a second face having at least two contact profiles. The filter cartridge is insertable into the box along an insertion direction substantially parallel to the first or second axis. The box includes a housing region between the wall and contact elements longitudinally spaced from the wall and axially spaced from each other. The plate group is housed in the housing region with the a sealing profile engaged with the wall and the contact profiles engaged to the contact elements. The sealing profile or contact profiles are shaped/positioned at variable vertical distances relative to an imaginary extension plane.

Abstract: A filter cartridge of a filter group of a fluid of a vehicle extends along a main axis including a base assembly and engagement members including first engagement members in the filter cartridge and second engagement members in the base assembly, respectively specially shaped to engage each other in a blocking configuration. The filter cartridge extends along a cartridge axis and includes at an axial end an engagement plane on which the first engagement members are made including at least two tooth elements diametrically opposite the cartridge axis. Each tooth element extends in height from the engagement plane extending on an imaginary surface parallel to the cartridge axis, having a substantially T shape. Each tooth element is elastically yielding in a radial direction, so that the blocking configuration is achievable following the radial movement of the tooth element.

Abstract: A blow-by gas filtration assembly has an axis and includes an assembly body including a filtration chamber, an inlet mouth for filtering the blow-by gases, and an outlet mouth for the filtered blow-by gases. A filter group includes a central cavity radially crossed by blow-by gases. An electric drive operatively connects to the filter group to command rotation about the axis and filtration, and includes an electric motor including a stator and rotor. An axial shaft includes a filter portion mounting the filter group, a command portion mounting the rotor, and a support portion axially between the filter and command portions. A support bearing radially engages the support portion and the assembly body. The filter assembly screwably engages the filter group and filter portion, by respective filter and shaft threads so the filter group screws to the shaft until the support bearing is axially engaged.

Abstract: A blow-by gas filtration assembly has an axis and includes a main body having a filtration chamber fitted with an outlet mouth at the axis. A filter group extends along the axis having a hollow cylindrical shape with a central chamber. An engine group operatively connects to the filter group for controlling its rotation about the axis. The engine assembly includes a rotor and a stator. A support and control shaft formed as a hollow body extends along the axis and includes an engine portion on which the rotor integrally mounts and a filter portion on which the filter group integrally mounts so that controlled rotation of the rotor corresponds to rotation of the shaft and thus of the filter group. The filter portion includes an outlet duct of the filtered blow-by gases inside which the outflow of the filtered blow-by gases towards the outlet mouth takes place.

Abstract: A water separation group is for a fuel filtration and separation assembly of a vehicle fuel circulation system. The assembly includes an assembly casing extending along a longitudinal axis positionable in the vehicle in a horizontal position and accommodating a filtration group for filtering dirty fuel. The water separation group is positionable in the assembly casing in fluidic connection with the filtration group and extends along a main axis parallel to and/or coincident with the longitudinal axis. The water separation group includes a separator and a blocking device below the separator to prevent return of separated water to the separator. The blocking device includes a blocking surface extending longitudinally forming an angle with the direction of the main axis that inclines at least a portion of the blocking surface to allow water separated from the fuel to flow towards the wall from which the blocking surface extends.

Abstract: A filter cartridge for a fuel circulation circuit of a vehicle.
The filter cartridge comprises a cartridge body identifying a filtration chamber. In said filtration chamber, the filter cartridge further comprises at least one filter insert which divides said filtration chamber into a dirty chamber containing fuel to be filtered and a clean chamber containing filtered fuel.
The filter cartridge further comprises a ventilation device suitable to ventilate in the dirty chamber, wherein the ventilation device comprises at least one ventilation duct placed in an upper area of the filtration chamber in which the air floating in the fuel accumulates. Said ventilation duct has a plurality of ventilation holes mutually spaced from one another through which the air is removed from the filtration chamber.
