    Abstract: The gear pump may have a casing, a main shaft and rotating means connected to one end of the main shaft and configured to rotate the main shaft. Housed by the casing, a toothed wheel and at least one other toothed element are intermeshed with the toothed wheel. The other end of the main shaft is connected to one of the toothed wheel and the casing. Rotating the main shaft relative to the rotating means rotates the toothed wheel and the at least one other toothed element relative to the casing, thereby generating the flow. The other one of the casing and the toothed wheel is configured to be rotated around an axis defined by the main shaft for varying a flow rate of the generated flow.

    Abstract: A hydrostatic drive system for vehicles may have a hydrostatic transmission unit with a hydraulic motor provided with a containment body and a drive shaft rotationally supported around a primary axis inside of the containment body. The system may also have an axle with a housing case for a differential device for the transmission of the drive torque to two half-axles and rotating around a secondary axis transverse to the primary axis. The differential device may also have a toothed conical drive ring gear in rotation about the secondary axis. The coupling member may be a conical pinion rigidly associated in rotation about the primary axis with the drive shaft and directly geared with the ring gear, the pinion being positioned along the terminal section of the drive shaft.

    Abstract: A swash plate bearing is disclosed. The swash plate bearing may have an arcuate cage member having at least one flange and a plurality of rolling elements rotatably coupled to the at least one flange. A coupling seat extends laterally from the at least one flange, the coupling seat may have an insertion hole. A link member may be rotatably coupled to the cage member, the link member having a central portion positioned between a first terminal portion and a second terminal portion. A first stem connects the central portion to the first terminal portion and a second stem connects the central portion to the second terminal portion. The central portion is positioned in the insertion hole.

    Abstract: A cartridge hand pump is disclosed. The cartridge hand pump comprises a housing; a lever extending from the housing; a cylinder provided in the housing wherein the cylinder is connected to a supply passage for receiving hydraulic fluid and to an actuator passage for sending pressurised hydraulic fluid; and a piston slidably positioned in the cylinder, the piston being operably connected to the lever for movement between a first position and a second position wherein the movement of the piston from the first to the second position sends pressurised fluid to the actuator passage characterised by a pressure relief valve accomodated in the housing wherein the pressure relief valve is in communication with the actuator passage such that pressurised hydraulic fluid is discharged through the pressure relief valve when pressure in the actuator passage exceeds a predetermined value.
