A closing device, particularly for closing channels conducting pressure medium in a valve receiving body, has a rotationally symmetrical closing element () that is fastened in a seating bore () of a housing (), having a calking site () that is provided on the circumference of the closing element () and that permanently fixes the closing element () in the housing () as a result of the plastic displacement of housing material. The seating bore () includes a transition area in the form of a bore step () between the calking site () and a centering cone surface (). The bore step is recessed into the seating bore () by the plastic displacement of the housing material in the form of a bulge surrounding the closing element ().

Closing device

The present invention relates to a closure device, in particular for closing ducts in a valve-accommodating member in which pressure medium is conveyed, comprising a rotationally symmetric closure member that is wedged in an accommodating bore of a housing. The calked joint is configured as a calking cone so that the accommodating bore forms a funnel-shaped contraction in the direction of the closure member, said contraction covering the periphery of the closure member in the area of a collar, and succeeding the calking cone is a second housing step that is expanded in relation to the first housing step, said step being formed by the housing material deforming plastically to the funnel-shaped contraction of the accommodating bore.

Anti-locking hydraulic brake system

A piston pump, having at least one delivery plunger to deliver pressure fluid from a suction chamber via a working chamber into a pressure port, is provided with elastic damping elements arranged in the suction chamber to compensate for the occurring pressure pulsations.

Hydraulic pump

In a hydraulic motor vehicle brake system with slip control comprising a pressure accumulator (13), a hydraulic pump (23), a non-return valve (2) and a brake power booster (17). The pressure outlet of the pump (23) is connected with the pressure accumulator and with an inlet of the brake power booster (17) via the non-return valve (2). The outlet side of the non-return valve (2) is connected with the inlet of the brake power booster (17) via the pressure accumulator (13) in order to reduce noises caused by pressure pulsations in the fluid flow of the pump (23).
