| 摘要 |
The present invention briefly refers to a braking force modulator for hydraulic vehicle brakes. The braking force modulator is intended to be inserted into the braking fluid conduit between the main cylinder or the like and one or more of the wheel braking cylinders and it is controlled by a sensoring system for performing the braking force modulation. The braking force modulator comprises a piston pump unit (12) with normally open inlet and outlet valves (37, 38) adapted to be closed under the action of a solenoid device (47, 48, 49, 52) whereby the unit is conditioned to act as a piston pump. The inlet and outlet valves (37, 38) are two mutually independent units adapted to be operated individually by means of one solenoid device each. |
