Title:
DEVICE FOR RENDERING OPERATIONAL A HYDRAULIC ACTUATING DEVICE
Document Type and Number:
WIPO Patent Application WO2004046573
Kind Code:
A8
Abstract:
The invention relates to a device for rendering operational a hydraulic actuating device, especially for a clutch of a motor vehicle. Said device comprises an emitter/receiver system (5) which is located in the hydraulic transmission path of the actuating device and contains two pistons (14, 16) having relative positions which can vary in relation to each other according to the desired operating behaviour of the actuating device. The aim of the invention is to improve one such device such that it can be rendered operational, in terms of the emitter/receiver system (5) to be filled with fluid, comparatively fast and with simple means. To this end, a fluid supply unit (24) contains at least one timing valve (25) which is used to release an essentially constant volume flow and is controlled by a timing valve control device (26) constructed in such a way that the volume flow of the fluid flowing into the emitter/receiver system (5) and released from the fluid supply unit (24) does not exceed a limiting volume flow (QK).
