Abstract: The disclosure relates to a hydrostatic axial piston machine having a housing, having a drive shaft, to which a flange disc is fastened in a rotationally fixed manner, and having a swash plate, to which a rotor disc, driven by the drive shaft or the flange disc, is rotatably mounted, and having a plurality of displacement units arranged distributed between the flange disc and the rotor disc and around the axis of the drive shaft, each displacement unit comprising a cylinder sleeve and a piston which extends into the cylinder sleeve and has a ball head and a spherical joint head which extends into the cylinder sleeve, wherein during operation, the piston plunges more or less far into the cylinder sleeve.

Abstract: A valve for a cold gas generator for an airbag in a vehicle includes: a valve chamber; a control chamber; a control piston; an overflow channel; a retaining element; and a shutoff element. The valve chamber includes an inlet from the cold gas generator and an outlet to the airbag. The control piston separates the control chamber and the valve chamber. The control piston is movable between an open position and a closed position, the control piston releasing the outlet in the open position and closing it in the closed position. The control piston has (i) a first active piston surface on the side of the valve chamber, and (ii) a second active piston surface on the side of the control chamber. The first piston surface is smaller than the second piston surface. The overflow channel fluidically connects the valve chamber and the control chamber to one another.

Abstract: A hydrostatic axial piston machine includes a drive shaft and a plurality of cylinder sleeves in which a spherical or ball-shaped section and a spherical or ball-shaped piston are inserted to delimit a respective displacer chamber. The sections are secured on a rotor, while the pistons are secured on a piston disk or piston drum. The piston disk is configured to be tilted at different pivoting angles relative to the rotor in a variable-displacement machine, or the piston disk is tilted continuously relative to the rotor in a constant-displacement machine. The rotor and the piston disk are coupled to one another for conjoint rotation by a driving device. The rotor and the piston disk can also be coupled indirectly by a drive shaft of the machine. A sliding joint axial with respect to a drive shaft is arranged between the rotor and the piston disk.

Abstract: A high-pressure pump (1), which serves in particular as a radial or inline piston pump for fuel injection systems of air-compressing, auto-ignition internal combustion engines, comprises a cylinder head (2) and a pump assembly (6). Here, the cylinder head (2) has a cylinder bore (4) in which a pump piston (5) of the pump assembly (6) is guided. Here, the pump piston (5) delimits, in the cylinder bore (4), a pump working chamber (12). Also provided is an inlet valve (20) which is integrated into the cylinder head (2) and via which fuel can be conducted into the pump working chamber (12). Metering of the fuel conducted into the pump working chamber (12) can be achieved by actuation of the inlet valve (20). Here, full charging of the pump working chamber (12) may take place. It is however also possible for partial charging of the pump working chamber (12) to be achieved by means of suitable actuation of the inlet valve (20).
