Abstract
A damper unit in which a structural volume of the unit is reduced. The hydraulic unit includes a damper chamber formed by a stepped bore. A diameter-to-length ratio of the chamber is between 1:3 and 1:12. A closure element of the damper chamber is received with radial pressure in the bore and is retained on the discharge end by an embossed connection. The smaller-diameter portion of the damper chamber bore, when the hydraulic unit is in the position for use, is offset eccentrically upward from the larger-diameter bore portion with an at least approximately horizontally extending bore axis, so that the jackets of both bore portion merge at least approximately in alignment with one another at at least one point. The damper chamber is of slender design and intended to be disposed in a housing block of the hydraulic unit in a way that economizes on installation space and is intended to be simple to vent. The hydraulic unit is intended for use in slip-controlled motor vehicle brake systems.
