Abstract: The invention relates to a device for a hydraulic unit, in particular in anti-skid systems for vehicle brake systems, which has a radial piston pump. The eccentric driven by a drive shaft in the pump meets pump pistons also located in the pump, usually in the region of high stroke variation speed. An resultant mechanical and hydraulic vibration, which causes noise and annoying movement at the brake pedal, is counteracted according to the invention in that a resilient intermediate element is disposed between the pump pistons and the eccentric element, and the eccentric is driven via a torsionally elastic coupling.

Abstract: A hydraulic radial piston pump especially for an anti-lock brake system for a vehicle has pistons (7) reciprocated by a cam (16) which is driven by a drive shaft (2). To counter the effect of the pump pistons (7) striking the cam (16) and also to counter the mechanical and hydraulic oscillations which cause noises and distracting brake pedal pulsations, a resilient intermediate element (18) is disposed between the pump piston (7) and the cam (16) and/or the cam (16) is driven via a torsionally resilient coupling (6). … …

Abstract: A hydraulic lifting apparatus for harvesting machines, the apparatus having a plurality of lifting cylinders connected to the undercarriage of the harvesting machine which support a mower table so that it rests on the ground with a minimal resting weight, and also having energy storing tanks to provide different suspension of the mower table. To accomplish this a hydraulically actuatable stop valve is located in a first circuit of working lines running between a distributing slide valve and the lifting cylinders. This stop valve is actuated by a control pressure which is branched from a second circuit of working lines. The second circuit of working lines runs from the distributing slide valve over a pressure relief valve to a reservoir, and is able to be disconnected by a solenoid valve. The stop valve has a valve element with a series of bores through which the pressure set by the pressure relief valve passes through the blocked first circuit of working lines into the lifting cylinders. Thereby the mower table automatically lowers with a preselected ground bearing force or selectively without the ground bearing force.

Abstract: The valve features a second return channel (91) for the working port (66), formed in the valve housing (10). The working port is controlled via the piston. The piston (70) and the shut-off valve (71) are installed in a longitudinal bore (28) running parallel to the bore (12) of the slide valve. The piston unlocks the shut-off valve and in this position opens the second return channel (91). The piston has a blind bore (82) with which a lateral bore (83) communicates.

Abstract: A hydraulic brake apparatus has two individually operable brake pedals (10, 15), which serve to modulate two traction vehicle brakes (14, 19) of a driven rear axle of a traction vehicle. A controlled check valve (23) is arranged between the brake master cylinder (12) operated by the first brake pedal (10), and a trailer brake valve (40). The second brake pedal (15) is operatively associated with the valve opening piston (32) of the valve (23). If the first brake pedal (10) alone is operated, then pressurised medium can flow only to the traction vehicle brake (19), because the valve (23) is closed. If the second brake pedal (15) alone is operated, then the valve (23) is opened. However, because the brake pedal (10) is not operated, no pressurised medium flows through the valve (23). If both brake pedals (10, 15) are operated simultaneously, then the trailer brake valve (40) is operated and the trailer brakes (48) come into operation. The brake apparatus is of simple and compact construction.
