摘要： A piston pump intended especially for use in a slip-controlled hydraulic vehicle brake system. The piston pump is inserted into a cylinder bore, the piston pump has a piston, a bush, and a closure element that tightly closes the cylinder bore. The closure element is joined radially movably to the bush, for instance via caulking. This joint has the advantage that the piston pump can be assembled into a compact, easily manipulated, and sturdy component unit, and that the closure element and the bush are aligned with one another on being inserted into the cylinder bore.

摘要： The invention is directed to a piston pump for a hydraulic vehicle brake system. For simple and inexpensive manufacturability, the piston pump embodies an outlet conduit as a groove in a sleeve bottom and a sealing part. As a result, the sleeve and the sealing part can be manufactured in a non-cutting manner by means of forming. Another advantage of letting the outflow conduit into the sleeve bottom is that the outlet conduit is disposed a small distance in the axial direction from a valve seat of an outlet valve, which counteracts noise production.

摘要： The invention relates to a piston pump having a piston that is axially displaceable in a bush. In order to keep the piston in the bush in a manner secured against loss, a tubular filter is secured to the bush in the extension thereof; the filter has a smaller inside diameter than the bush and in this way keeps the piston in the bush.

摘要： A piston pump, which is provided as a return feed pump for a slip-regulated motor vehicle brake system. In order to simplify the manufacture, a sleeve in the form of a tubular piece is clamped between a fastening element which is inserted into the cylinder bore using a self-clinching technique, and the cylinder bore, and is thus sealed and fixed in place. In addition to the simple manufacture of the sleeve out of reasonably priced tubular material, the piston pump has the advantage of a sealing of the sleeve in the cylinder bore without a separate sealing element such as a sealing ring.

摘要： A piston pump with at least one driven stepped piston element disposed longitudinally movably in a housing is disclosed. The piston element and housing define a plurality of pressure chambers whose volumes vary as a function of the motion of the stepped piston. A volume of the first pressure chamber is decreased during an intake stroke of the piston that increases the volume of the second pressure chamber. A volume of a third pressure chamber, communicating with the pumping side and defined by the stepped piston element and the housing, is increased by a defined volumetric value during the compression stroke and decreased by the during the intake stroke; the defined volumetric value is less than the change in volume of the second pressure chamber during the compression stroke of the stepped piston element.

摘要： The invention relates to a pump assembly for a hydraulic brake system with traction control, having an electric motor and a piston pump. To reduce a bearing load, the invention proposes rotatably supporting and thereby radially bracing a motor shaft, or an eccentric sleeve pressed onto the motor shaft, on both sides of pump pistons. To economize on installation space, a pump bearing is disposed in an end of the eccentric sleeve that protrudes past the motor shaft.

摘要： A piston pump for pumping hydraulic fluid, especially for vehicle brake systems having a stepped piston axially displaceable in a pump space. The stepped piston in order to reduce the production costs comprises a cylinder of substantially constant outer diameter and a bush which is held axially nondisplaceably on the cylinder, by being press-fitted onto the cylinder. An elastomer seal is slipped onto a cylinder portion defined by the bush seals off the cylinder from the wall of the pump space and divides the pump space into two pump chambers of variable chamber volume.

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.
