摘要： This invention relates to a radial piston pump in whose suction bore (22) a load regulator (24) is inserted. The pump is to be regulated so that a constant stream and, as required, a variable large regulating stream will be available. For this purpose, a spool valve (26) that can be activated electromagnetically is inserted in a bore (23) that intersects the suction bore (22) and that spool valve can establish a connection to a suction duct (28) that is connected to a cam chamber (14) to make the regulating stream available by means of a collar (33). From suction bore (22) there furthermore branches off a shutter bore (34) that is likewise connected to the cam chamber (14) via a ring groove (35) and additional bores (36) in the pump housing (3). Shutter bore (34) limits the constant stream. The regulating stream is supplied to a consumer with fluctuating power consumption, for example, a hydrofan, that is powered with an rpm proportional to the cooling water temperature. The constant stream is used to supply, for example, a level regulation and lubricating stream. The load regulator (24) as well as the oil guides (bores, ducts, ring grooves) are machined into a cover (2).

摘要： An automatic transmission, in particular an infinitely variable automatic transmission for motor vehicles, contains a radial piston pump (1) for supplying a hydrodynamic converter (3), a lubricating device and control and actuating devices of the automatic transmission via a number of control conduits. Radially outside of its outlet valves, the radial piston pump (1) contains an annular chamber (22), which extends around the radial piston pump (1). The annular chamber (22) is embodied as a damping chamber and is mainly arranged in a recess (23) of the converter housing (2), and therefore almost completely outside of the pump housing (17). The annular chamber (22) is bordered by the recess (23) of the converter housing (2), the pump housing (17) and/or a separate pump cover (24). The annular chamber (22) is not symmetric and with its volume extends into the adjoining free spaces of the automatic transmission.

摘要： A gear for motor vehicles provided with a positive-displacement pump for supplying a lubricating device and the control and activating devices of the gear. The positive-displacement pump is driven by the rotation of a drive motor and is provided with a suction throttle which adjusts the flow of lubricating oil such that a relatively constant flow is maintained over a varying range of rotational speeds of the drive motor. The invention provides the advantages that gear efficiency can be improved since high rotational speeds of the drive motor do not cause a excessive flow of lubricating oil.

摘要： A radial piston machine, e.g., a radial piston pump, in which an eccentric, rotatable on a stationary axle, drives multiple radially arranged pistons via an external sliding ring. Since a pump of this type operates with intake regulation, the delivery chambers are only partially filled above a middle speed range. Therefore, pressure surges, which cause noises, arise upon the impact of the piston on the oil volumes to be pushed out. These pressure surges may be reduced if a flexible circlip is positioned between the external sliding ring and the eccentric. Such a circlip allows the piston to deflect slightly together with the external sliding ring at the beginning of the pressure stroke, so that pressure peaks are suppressed and the noises are reduced. The flexibility of the circlip is increased using openings, which are positioned along the central axis, i.e., in the plane of the piston axle.

摘要： The radial piston pump has a number of cylinder bores in a pump housing to accommodate pistons which slide into them; the cylinder bores are plugged by pressed-in stoppers (3) in which pressure channels are incorporated, all stoppers being sealed by a flat spring (6) which serves as return valve. To enlarge the outflow cross section through the pressure channels, each stopper 3 has at least one side discharge channel (8, 9).

摘要： An axial piston pump for supplying two separate oil circuits including two pistons units (6, 8) of which one is situated upon an external circle and the other upon an internal circle. The external piston unit (6) must be regulatable so that it can feed a hydromotor of a radiator fan. The internal piston unit (8) must supply a level regulation with a constant flow of oil. Accordingly, both piston units (6 and 8) suck oil via separate suction bores (11 and 26). In the suction bore (11) of the external piston unit (6) leading to the swash-plate chamber (4) is inserted an electromagnetically actuable controlling valve (12). In order that the pistons (5) of the external piston unit (6) cannot run dry when the controlling valve (12) is regulated, there branches off from the suction bore (11), upstream of the controlling valve (12), a constant-flow bore (23) which via an annular groove (24) and radial bores (25) supplies a relatively small amount of oil to each piston (5) in the dead-center position thereof. The pistons (7) of the internal piston unit (8) receive the oil via an annular groove (27) branching off from the suction bore (26) and discharging in the cylinder chambers (7A) via radial bores (28). The radial bores (28) are open in the lower dead-center position. In this manner pressurized oil can be fed separately to each piston unit without mutual interference. Pressure channels (13A and 30A) of both piston units (6 and 8) discharge in a common sealing surface (35) of a piston carrier (10). In the annual grooves (14 and 31) of a rear housing part (40) exhaust valves (13 and 30), respectively, are located consisting of a ring plate (33, 34) and a rubber elastic ring (36 or 37) and tightly fitting against the sealing surface (35).
