摘要： The invention relates to a piston pump for a slip regulating device in a hydraulic automobile brake system. For a more economical production, the invention provides a piston (40) of the piston pump to be constructed as a composite piece with a core (42). The core (42), for example, can be made of steel and surrounded by a plastic sliding case (44). The sliding case (44), for instance, can be placed on the core (42) by means of extrusion-coating and can also be pressed or pushed onto the core (42). The sliding case removes the need for costly subsequent machining of the piston surface, for example through grinding, and improves the sliding properties of the piston (40).

摘要： The invention relates to a pressure accumulator (12), especially for a hydraulic unit of a hydraulic vehicle braking system with electronic wheel slip regulation. Pressure accumulators (12) comprising an accumulator piston (22) acted on by a piston spring (36) are known according to prior art. In order to save costs on parts for the piston spring (36) and to save space in terms of the pressure accumulator (12), a piston spring (36) comprising at least one first spring winding (40) is used, the outer diameter of the winding being smaller than the inner diameter of a second spring winding (42) connected thereto.

摘要： The invention relates to a piston pump (10) which is especially provided for a slip regulated hydraulic vehicle brake system. The piston pump (10) is arranged inside a cylinder bore (12) and contains a piston (16), a cylinder sleeve (26) and a sealing closing component (68). According to the invention, the closing component (26) is radially and movably connected to the cylinder sleeve (26), for instance, through a support (70). One advantage provided is that the piston pump (10) can be assembled with a compact, easy to manage and robust structural component so that the closing component (68) and cylinder sleeve (26) are aligned with one another when they are installed in the cylinder bore (12).

摘要： The invention relates to a pump aggregate (10) for a hydraulic vehicle braking system with a slip control device. The pump aggregate (10) has an electromotor (12) and a radial piston pump (14) which can be driven with the electromotor (12). The invention provides that a rotor shaft (18) of the pump aggregate (10) is configured with a hollow shaft (20) and two standardized, hardened cylindrical pins (22, 24) which are pressed into the ends of the hollow shaft (20). The invention has the advantage that the rotor shaft (18) can be produced simply, economically and without cutting. As a result of the hollow shaft (20) configuration, the rotor shaft (18) has a high degree of flexural and torsional strength. The pressed-in pins (22, 24) give the rotor shaft (18) a small diameter at the bearings, allowing a small bearing diameter and therefore, a small construction volume for the pump aggregate (10).

摘要： The invention concerns a piston pump (10) to be used for example in a vehicle antiskid hydraulic brake system. The aim of the invention is to enable economical production of said pump (10). To this end, a packing (16) is produced in a single piece with a base (18) having a seat valve (22) for the piston pump (10) outlet valve (50), said packing being produced in the form of a cold headed piece, without undercut. Moreover, the assembly is simplified since a tight fit is provided for the closure cap (66) and its stop at the packing (16). The fluid under pressure leaves the pump via circulating channels (70) provided therefor in the closure cap.

摘要： The invention relates to a piston pump (10) for a hydraulic vehicle brake system. According to the invention, an outlet duct (90, 94, 96) formed as a groove in the base of the cylinder (64) and a closing component (68) are configured in order to simplify and reduce the cost of production. This enables the cylinder sleeve (26) and the closing component (68) to be produced without cutting by reshaping. One advantage of mounting the outlet duct (90) in the base of the cylinder (64) is that it is arranged in an axial direction close to the seat (84) of an outlet valve (82) thus counteracting the production of noise.

摘要： The invention concerns a piston pump (10) for a vehicle antiskid hydraulic brake system. The invention aims at the economical production of said pump piston (20, 22). To this end, the piston is produced from a part obtained by forming (20) and a closure plug (22) driven in by a pin (42) into said part (20). The advantage of the invention lies in the fact that the piston (20, 22) can be produced without elimination of material, therefore quickly and economically, in the form of a piece obtained for example by extrusion.

摘要： The invention relates to a piston pump (34) especially for a hydraulic slip regulating device of a motor vehicle braking system. In order to reduce the clearance volume of the piston pump (34), the invention provides a displacement body (104) fastened by means of a retaining device (98) onto the piston (66). The displacement body (104) is projected into the interior area of a valve closing spring (92) configured in the form of a coil of the inlet valve (88) that is integrated within the piston (66). The rectangular shaped coil cross section construction of the valve closing spring (92) and of the piston return spring (72) serves to reduce the clearance volume of the piston pump (34). The reduction of the clearance volume increases the efficiency of the piston pump (34).
