Abstract:
An assembly (10) of auxiliary apparatus for an internal combustion engine comprises a coolant pump (16), an oil cooler device (12) and an oil filter (14) unit combined and interconnected as a constructional unit for mounting on the internal combustion engine. The oil cooler device (12) comprises a housing (18) having an oil pathway and a coolant pathway (34), the pathways being arranged to allow heat exchange between oil and cooling flowing through said pathways. The housing (18) has a mounting surface (26) for attachment to an internal combustion engine, such that the oil pathway and the coolant pathway each extends beyond the mounting surface to be located, in use, within a recess in a wall of engine. The assembly (10) allows the engine envelope size to be reduced. The invention also relates to an internal combustion engine including the assembly and a unitary base structure for the assembly.
Abstract:
Disclosed is a subassembly for an appliance driven by an internal combustion engine, the components of which are assembled in the form of a module (1), with the fastening means to associate the module to the internal combustion engine.
Abstract:
A heat exchanger (4) for cooling a machine, such as a mechanical gear or some other transmission component, hydraulic pump, motor or clutch, compressor, internal combustion engine or like machine, which comprises a housing (1) in which movable, mechanical elements (2), which are driven when the machine is working, are housed and which encloses a liquid medium (3), such as a lubricating or hydraulic liquid. The heat exchanger is mounted in the outer wall (5) of the housing and comprises two chambers (6, 7) which are mutually separated by a liquid-impervious partition wall (8) wich comprises part of the housing wall. The inwardly located chamber (7) is through-passed by the liquid medium (3) enclosed in the housing, while the outwardly located chamber (6) is through-passed by a cooling medium. The heat exchanger (4) is so positioned that a pressure difference is created between the inlet (13) and the outlet (16) of the inwardly located chamber (7) under the influence of movement of the movable mechanical elements (2) therewith obviating the need of a separate pump for driving the medium (3) to be cooled through the heat exchanger.
Abstract:
A combined filter and heat exchanger for simultaneous filtering of a first medium and heat transfer between the first medium and a second medium, for example a combined oil filter and cooler for internal combustion engines includes a filter section comprising a hollow, cylindrical filter element (2) arranged co-axially within an outer casing (1) having a cylindrical wall (1a) which extends around the filter element coaxially therewith and in spaced relationship thereto. A heat-exchanger section is arranged in the space between the cylindrical wall (1a) and the filter element (2). The heat-exchanger section includes a cylindrical partition wall (5) subdividing said space into two chambers. The first medium flows first through the inner chamber and is then distributed across the outer surface of the filter element (2), whereas the second medium flows through the outer chamber (7).

Abstract:
Apparatus is disclosed for lubrication of the operating components of an internal combustion engine with accelerated heating of the lubricant during engine warmup, comprising (i) a primary circuit for lubricant recirculation including a primary reservoir (11) adapted to receive lubricant drainage from the engine and a primary conduit (16) adapted to return lubricant to the engine (10), (ii) means (17) for pumping lubricant through the primary conduit (16) to the engine (10), (iii) means for preheating the lubricant with heat produced by the engine employing a heat exchanger (18) along the primary conduit (16), and (iv) an auxiliary lubricant reservoir (14) and a return conduit (23) providing fluid communication for the flow of lubricant from the auxiliary reservoir (14) to the primary reservoir (11). A valve (27) in the return line is controlled to permit flow of lubricant to the primary reservoir (11) in response to a drop in the primary reservoir (11) lubricant level. Means (21, 22) are provided for selectively diverting lubricant from the primary circuit to the auxiliary reservoir (14) following engine warmup when the temperature of the lubricant in the primary circuit reaches a preselected operating temperature.
Abstract:
An oil cooler (1) is removably mounted on the side of an engine block (13) with a tubular coolant flow coupling (19) received as a push-fit in an aperture (18) in the block so that the coolant flow connection is simply made as the oil cooler is fastened to the side of the block. The coupling (19) may be a push-fit in respective axially aligned apertures (18, 20) in the block and the cooler. The flow coupling may be an inlet coupling for coolant from the block. The end of the coupling that cooperates with the block has an extension (24) that projects into a coolant flow passage (17) in the block and is shaped to form an inlet opening that is directed laterally of the axis of the coupling and upstream of the coolant flow in said passage. The extension (24) collects coolant from said passage and produces a pressure drop in said passage. A coolant return-flow coupling (28) is provided between the oil cooler (1) and the block (13) and opens into said passage (17) downstream of said inlet coupling (19) so that said pressure drop assists the flow of coolant through the cooler.
Abstract:
Fail-safe oil flow control apparatus includes a thermally responsive actuator (24) operable to displace a tubular valve member (70) so as to control lubricating oil so that it flows either directly to an engine, or to the engine through an oil cooler, in accordance with the oil temperature conditions which exist. The apparatus also includes a spring (40) which controls operation of the valve member (70) in accordance with the oil pressure conditions which exist. The apparatus also includes a fusible body (50) which melts and permits operation of the valve member when excessive temperatures exist in the apparatus.
