    摘要： The present invention relates to an eccentric arrangement for a reciprocating piston pump, having a drive shaft drivable by a drive device, an eccentric part of a rubber-elastically deformable material is disposed on the drive shaft in a manner fixed against relative rotation. A bearing ring is provided on an outer circumferential surface of the eccentric part, by which ring a reciprocating piston is displaceable driven substantially perpendicular to the drive shaft. To avoid stroke losses, first and second support faces are provided on the drive shaft which the eccentric part disposed between them in such a way that the eccentric part rests with its axial ends on the first and second support faces.

    摘要： The invention seeks to reduce structure-borne sound emissions of the reciprocating piston pump. The reciprocating pump is includes an outlet valve, which has a valve seat and a valve closing body that is received in a hollow space and is loaded by a closing spring. One outlet bore radially originates at the circumferential region of the valve seat and branches off from the hollow space. The opening of the outlet bore toward the hollow space extends at least approximately between the valve seat and the end toward the closing spring of the gap of least cross section, which is formed between the valve closing body and the inside circumference of the hollow space. As a result, a slowed opening motion of the valve closing element is attained, in which opening motion an opening gap opens up that has its largest flow cross section in the region of the outlet bore. The supply flow, which increases slowly as the outlet valve opens, results in a slowed force variation speed in the drive train of the reciprocating piston pump and a reduced emission of structure-borne sound. The pressure fluid pumping device may be used for instance in hydraulic motor vehicle brake systems having an anti-skid system and/or traction control system.

    摘要翻译： 本发明旨在减少往复式活塞泵的结构传播声发射。 往复泵包括出口阀，其具有阀座和闭合阀体，所述阀座和阀关闭体容纳在中空空间中并且由闭合弹簧加载。 一个出口孔径向起始于阀座的圆周区域并从中空空间分支出。 出口孔朝向中空空间的开口至少大致在阀座与靠近中空空间的内圆周之间形成的最小截面的间隙的关闭弹簧的端部之间延伸。 结果，实现了阀关闭元件的缓慢的开启运动，其中打开运动开口间隙在出口孔区域中具有最大的流动横截面。 随着出口阀打开，供应流量缓慢增加，导致往复式活塞泵的传动系中的减速力变化速度减小，结构声音的排放减少。 压力流体泵送装置可以用于例如具有防滑系统和/或牵引力控制系统的液压机动车辆制动系统中。

    摘要： The invention is based on a reciprocating piston pump having two radial pistons disposed symmetrically to one another, which are drivable to a reciprocating motion by an eccentric disposed between them and are held in contact with the eccentric by a hoop spring that engages the pistons. For ease of installation, the invention proposes embodying the hoop spring as a bent wire part, with two open, hooklike eyelets on their ends, which ends are inserted into annular grooves of the pistons and enter into a snap connection with them in order to hold the pistons tightly against the eccentric.

    摘要： The brake system has at least one brake circuit (I), in which a high-pressure pump is disposed. A self-aspirating charge pump is also provided, which is connected at least indirectly to the intake side of the high-pressure pump by an intake line of a supply container for brake fluid and by a pressure line. In the event of an inadequate supply of brake fluid by the charge pump, the pumping of air into the brake circuit (I) is intended to be precluded. To that end, a siphon is disposed in the intake line of the charge pump. Air aspirated by the siphon suddenly prevents pumping by the charge pump. The brake system is intended for use in motor vehicles with slip control or for automatic brakes.

    摘要： An oscillation damper that has a cup-shaped elastomer diaphragm body, with a bottom diaphragm. The diaphragm body is received tightly on an opening side in a bore of a housing, and fits around a protrusion of a closure body that closes the bore. Between the closure body and the diaphragm, a support body having an end face that is concave toward the diaphragm is received in the diaphragm body. A void formed between the diaphragm and the support body communicates with the atmosphere, through a conduit embodied on the support body and through an opening in the closure body. The oscillation damper can be used in hydraulic slip-controlled motor vehicle brake systems.
