摘要： A hydraulic energy accumulator consisting of a housing (7) with a space (4) for inserting metal bellows (5), comprising a non-moveable end and a moveable end with a front wall arranged in a sealed manner on the bellows and separating a hydraulic pressure medium from a pressurized gas is already known per se. The advantage of using metal bellows is that they are gas-tight in so far as no leak arises over time. According to the invention, the bellows are embodied in such a way that the pressure of said bellows in the gas is reduced in comparison with the hydraulic medium as a result of the longitudinal elasticity of said bellows and a sensor system (6) is provided which indicates a longitudinal expansion of the bellows (5) when the hydraulic pressure medium flows through a leak in said bellows into the area containing the gas. The inventive hydraulic energy accumulator (2) and the sensor system (6) thereof are also capable of indicating when such a leak occurs in the bellows. The indication of a leak is also an indication that a motor vehicle braking system fitted therewith has become unsafe.

摘要： The invention relates to a piston pump for conveying fluids, comprising a piston (2) and a pressure chamber (3) located between an intake valve (4) and a discharge valve (16). The intake valve (4) is arranged between the pressure chamber (3) and a low-pressure zone (20) of the piston pump while being provided with a valve body (5), a closing element (6), a device (8) for preloading the closing element (6), and a device (10) for fastening the intake valve to the piston (2). The fastening device (10) encompasses at least two fastening elements (11, 12, 13, 14) which protrude from the valve body (5) in the direction of the piston (2), are positioned at a distance from one another, and are fitted with inlets (15) therebetween for supplying fluid. The invention further relates to a piston pump comprising an intake valve without a spring-biased element.
