Abstract
A pulsation damper for damping pressure medium vibrations in a hydraulic system, has a membrane within a bore of a housing, which membrane is exposed to the pressure medium on its one side and faces a gas-filled cavity inside the housing on its other side, the bore of which is closed by means of a plug. The membrane, in conjunction with the plug and a hollow-cylindrical support body, forms an independently handleable, functionally pre-testable assembly, for which purpose the membrane is substantially cup-shaped, and the support body extends into it.
Claims12
A pulsation damper for damping pressure medium vibrations in a slip-controlled motor vehicle brake system comprising:
- a membrane within a bore of a housing, wherein membrane is exposed to the pressure medium on one side and faces a gas-filled cavity inside the housing on an opposing side, wherein the membrane is cup-shaped and has at least one of grooves and ribs defined on the circumference thereof;
- and
- a cup-shaped plug to close the bore of the housing, wherein the membrane and the plug form an independently handleable, functionally pre-testable assembly, wherein the membrane has a sleeve-shaped extension which completely encloses a tubular section of the plug along its outer circumference;
- and
- a plurality of ribs run in the longitudinal direction on the circumference of the membrane between the tubular section and the cup-shaped region of the membrane.
