A pump assembly for supplying negative pressure to a pneumatic brake booster, wherein the pump assembly has at least two elastic displacement elements which are moved by connecting rods, the connecting rods each being rotatably mounted on an eccentric element. The eccentric element has a bearing seat element and a force element. At least two eccentric elements are secured next to each other on a drive shaft that rotates about an axis of rotation and an interlocking anti-rotation device is provided that determines a defined angular position of the eccentric elements relative to each other about the axis of rotation. In order to improve the ease of assembly and simplify the manufacturability, the anti-rotation device is designed as shaped elements of the bearing seat element in such a way that they engage in each other in an interlocking manner when the eccentric elements are in a defined angular position relative to each other.

A cylinder aligning sleeve and adapter plate for use within an internal combustion engine. The sleeve includes apertures placed contiguously with holes within the adapter plate to form a flow passage through the dead space between compression and crosshead pistons. The flow passage exits to a vent line where gas detection may occur along with safe venting of any gas detected. The sleeve serves to ensure concentric alignment of the compression cylinder with the engine block bore.

A pump or compressor includes a rotating shaft, and at least a first piston rod substantially perpendicular to the rotating shaft and connecting a first pair of pistons at opposite ends of the piston rod. The piston rod moves back and forth relative to the rotating shaft. The compressor additionally includes a circular eccentric, and a circular ring connected to the circular eccentric via a bearing. A drive pin engages the circular ring at a fixed position on the circular ring and engages the at least a first piston rod. When rotational motion of the shaft rotates either the first piston rod and first pair of pistons or the circular eccentric, the drive pin and the first piston rod move back and forth relative to the rotating shaft.

The present invention relates to a working engine that comprises a working volume or plurality of working volumes. The working volume(s) are each assigned one or more inlet valves and one or more outlet valves. The inlet valve(s) are connected to a supply line arrangement that supplies a medium. The inlet valve(s) are arranged so that when an inlet valve is open, the medium is supplied to the working volume assigned to the inlet valve. The outlet valve(s) are connected to a discharge line arrangement. In the working phase of increasing the working volume(s), the inlet valve(s) associated with the working volume(s) are open and the outlet valve(s) associated with the working volume(s) are closed. In the working phase of reducing the working volume(s), the outlet valve(s) associated with the working volume(s) are open and the inlet valve(s) associated with the working volume(s) are closed.
