    摘要: The invention relates to a pump for delivering a fluid, especially a vane-cell pump, comprising a delivery device (1) which is accommodated in a casing (2). The casing (2) is closed on one side by a casing cover (3), and the other side is connected to a bearing flange (4). An input shaft (11) passes through the bearing flange (4), the delivery device (1) and optionally through the casing cover (3). In addition, said input shaft is mounted in a passage which is configured in the bearing flange (4) and optionally configured in the casing cover (3). A side plate (16, 17) which is supported against the inner wall, and which centers the delivery device (1) in the casing (3) is respectively arranged between the delivery device (1) and the inner wall of the bearing flange (4) and optionally of the casing cover (3). The aim of the invention is to provide an easy centering of the side plate (16, 17), especially while reducing reference tolerances with regard to the casing (2). To this end, the side plate (16, 17) is centered directly in the passage for the input shaft (11) on the side facing the bearing flange (4).

    摘要: The invention relates to an axial piston motor (1), especially a compressor for the air conditioning system of a motor vehicle, comprising a housing (2) and a compressor unit (6). Said compressor unit is driven by a drive shaft (8), is arranged in the housing (2), and is provided for sucking and compressing a cooling medium. The compressor unit (6) comprises pistons (15) which move in a reciprocating motion in a cylinder block (18) and comprises a drive disc (11) which rotates with the drive shaft (8) and which drives the pistons (15). The aim of the invention is to obtain a delivery rate which is independent of rotational speed. To this end, the invention provides that the mass of the drive disc (11) is calculated such that the centrifugal forces generated when the drive disc (11) is rotating are large enough to counteract the pivoting movement of the drive disc (11) while actively regulating the same, and to influence the piston stroke and thus the delivery rate, especially to reduce or to limit the same.

    摘要: A vane-cell pump has a rotor that receives a plurality of radially movable vanes, a lifting ring which surrounds the rotor and forms at least one suction and one pressure region, and at least one compression plate which forms a lateral delimiting surface of the suction and pressure regions. When the vane-cell pump is in operation, a pressure is applied to the side of the compression plate opposite to the suction and pressure regions. The vane-cell pump is characterised in that the surface (17; 19) of the compression plate (13; 15) which faces the rotor (5) has a concave shape in the unpressurised state of the vane-cell pump (1).
