摘要: A piston pump for a slip-controlled, hydraulic brake system of a vehicle. A hollow piston is provided with an inner piston seal that has a sealing lip. During an upward reciprocating motion of the piston, fluid can flow past the sealing lip in a direction of a piston inner (displacement chamber) and constitutes an inlet valve of the piston pump. During a downward movement of the piston the sealing lip is forced by pressure against an inner surface of the piston to prevent a flow of fluid past the sealing lip. The invention obviates the need for a separate inlet valve and makes it possible for the piston pump to be short in length.

摘要: A piston pump for a hydraulic brake system of a vehicle with slip control. The piston pump has a piston which is received in a bush that is inserted into a cylinder bore of a pump housing that is closed in pressure-tight fashion by a closure part. For simpler assembly, the closure part is connected to the bush by means of a snap or detent connection. As a result, a preassembled unit that can be manipulated easily before insertion into the pump housing is obtained in a simple way.

摘要: The invention relates to a piston pump with a piston (10) that is guided so that it can move axially in a pump bore (12) of a pump housing (14). In order to simplify the manufacture of the piston (10), the invention proposes providing the piston (10) with a support ring (64), which is connected to a guide ring (66). By connecting the support ring (64) and guide ring (66), the structural length of the piston pump (10) can be shortened.

摘要: This invention is directed to a closing member of an inlet valve of a pressure-medium-traversed piston of a reciprocating piston pump. The closing member is disposed as fully as possible in the piston to minimize the dead air space. The piston has a longitudinal bore in which a stem engages the closing member, which stem emanates from a valve disk. The stem is embraced by an at least approximately frustoconical helical compression spring acting as a closing spring. This is held, with an end segment of smaller diameter, non-twistably against the stem. A shoulder of the longitudinal bore is located on the valve seat side and exhibits at least one cross-sectional alteration for the screw-like action upon the end segment of larger diameter of the closing spring. The closing spring is thus able to be sunk into the longitudinal bore and biased in place. The reciprocating piston pump can be used, for example, for slip-regulated braking systems of motor vehicles.
