Abstract:
PCT No. PCT/EP96/04587 Sec. 371 Date May 5, 1998 Sec. 102(e) Date May 5, 1998 PCT Filed Oct. 22, 1996 PCT Pub. No. WO97/15481 PCT Pub. Date May 1, 1997A brake master cylinder (10) for a hydraulic vehicle brake system has a master cylinder housing (32) and at least one pressure chamber (40) designed therein. Connected to the pressure chamber (40) is a hydraulic fluid reservoir which, furthermore, is provided for connection to a precharge pump of a brake pressure regulating system. Moreover, the brake master cylinder (10) has a hydraulic fluid return connection (30) which makes a fluid connection between the delivery side of the precharge pump, the reservoir and the at least one pressure chamber (40). A throttle (60) is arranged in this liquid connection, said throttle not impeding a hydraulic fluid stream out of the reservoir into the at least one pressure chamber (40) and throttling a hydraulic fluid stream from the return connection (30) into the reservoir. The throttle (60) makes it possible to cause the precharge pump to act on the at least one pressure chamber (40), without an electromagnetic valve being interposed.
