摘要： A pressure limiting valve has a valve closing member (ball), which is subjected to a hydraulic opening force and is indirectly subjected to a closing force generated by a compression spring which avoids hysteresis that impairs the switching behavior of the pressure limiting valve. A tappet, which passes through a sealing ring and is exposed to a control pressure, is also capable of acting in a closing manner upon the pressure limiting valve. When there is no operative control pressure, the tappet is pushed back by the opening of the pressure limiting valve and is retained in this position by frictional forces brought about by a sealing ring. The switching plays of the pressure limiting valve are free of frictional forces. The pressure limiting valve is suitable for use in hydraulic motor vehicle brake systems.

摘要： A hydraulic system having a pressure generator which is protected against destructive overload. The hydraulic system has a pulsating feeding pressure generator, such as a piston pump, which feeds pressure fluid at high pressure into a damper chamber of a housing. A throttle body having a throttle bore is disposed on the outlet side of the damper chamber. For producing the protective effect, the damper chamber is preceded by a rupture disk communicating with the outlet. The throttle body suitably has a thin-walled portion, embodied as a rupture disk, in which the throttle bore is located. The embodiment described is advantageously usable in hydraulic systems in which pressure fluids are pulsatingly fed at high pressures.

摘要： A piston pump for brake systems employs a pulsation-smoothing device that functions especially well in the region of the outlet valve. As a result, substantially less noise occurs, and the durability of the piston pump is substantially better. The piston pump is used essentially in traction-controlled motor vehicle brake systems.

摘要： A motor-and-pump unit having an electric motor in combination with a housing of the pump. The pump has at least one displaceable pump piston. To that end, on the side toward the pump housing and originating at one end wall, the electric motor has a bearing neck, which is tubular and into which the pump housing protrudes. This bearing neck fixes an outer ball bearing race of a ball bearing for a shaft of the electric motor. Protruding from the ball bearing is a shaft end that carries an eccentric element for moving the at least one pump piston. The eccentric element is disposed at an axial spacing from an inner ball bearing race that surrounds the shaft in stationary fashion. The eccentric element is brought directly up to the inner ball bearing race, and the inner ball bearing race and the eccentric element are embodied as a one-piece, multifunctional component. This one-piece construction offers the advantage that both the inner ball bearing race and the eccentric element firmly surround the end of the shaft like a reinforcing sleeve and thus reinforce this shaft end. Furthermore, bringing the eccentric element close to the ball bearing reduces the bending moment that tends to cause warping.

摘要： A brake system that includes a power-actuated service brake and an auxiliary brake that is actuated by muscle power. To achieve a desired characteristic curve of the pedal when the service brake is actuated, a path simulator is provided in a master cylinder. This path simulator has compression springs disposed in a pressure chamber. The pressure chamber is defined by a floating piston with a seat valve, which controls a pressure fluid-carrying connection of the pressure chamber to a pressure fluid reservoir of the master cylinder. The function of the seat valve is dependent on the stroke of a rod piston, which can displace pressure fluid from a first pressure chamber when the auxiliary brake is actuated. The path simulator is active if pressure fluid is not displaced from the first pressure chamber during the actuation of the service brake and therefore the seat valve assumes its open position.

摘要： The invention relates to a piston pump with a piston received axially displaceably in a pump bore. To improve the aspiration performance of the piston pump. A cuff with a U-shaped annular cross section is provided, the cuff is inserted into the pump bore surrounding the piston, an outer lip forms a diaphragm, which rests against a wall of the pump bore and is acted upon on its outside with ambient pressure through a venting bore. The cuff is part of a fluid storage element, which makes an additional fluid volume available to the piston pump. The diaphragm acted upon by ambient pressure creates a pumping effect, if a fluid pressure in the fluid storage element drops below ambient pressure in an intake stroke of the piston.
