Abstract:
1. A supply device for the supply of pressure fluid into at least one vehicle brake comprising: a piston movably arranged in an accommodating member, a carrier bearing a non-return valve arranged coaxially with respect to the piston for ventilating a working chamber into which the piston plunges, a resetting spring arranged between the carrier and the piston, a multi-part cage assembly comprising a plurality of separate cage parts for accommodating the resetting spring into the plurality of separate cage parts, wherein the resetting spring is caged and simultaneously elastically preloaded under the relative displacement of the plurality of separate cage parts, fastening means for locking the multi-part cage assembly comprising at least two locking arms formed on a first cage part and at least two holes formed on a second cage part, each locking arm of the first cage part having a resiliently deformable and unconstrained end configured for engaging a hole of the second cage part upon relative displacement of the first and second cage parts, wherein one of the first and second cage parts has a cylindrical wall forming a carrier-side engagement area with which the multi-part cage assembly is accommodated in the carrier such that the multi-part cage assembly forms a modular unit, and wherein a carrier-side accommodating area of the one of the first and second cage parts is axially spaced from the fastening means of the plurality of separate cage parts.
