Abstract

PURPOSE: To prevent noise caused from flow of liquid by independently providing two pieces of throttling parts on the valve part.
CONSTITUTION: When a control rod 31 is swiveled clockwise taking a fulcrum 32 as its center at the time of braking, a plunger 21 moves to the side of a power piston 6, and at last the end surface of a valve part 21a contacts the rim of a flow passage 8 of the power piston 6. By doing so, liquid is throttled through an influent port 2 by throttling grooves 27, 27' and poured into the flow passage 8. Since the throttling grooves 27, 27' have the external ends 27a, 27a' opened to the periphery of the valve part 21a, and the internal ends 27b, 27b' are closed by a pin 26, flows of liquid led through the throttling grooves 27, 27' via upstream side to the flow passage 8 are respectively independent, without event of frontal collision at the place, make confluence in the flow passage 8. This reduces noise which is due to the flow of liquid through the throttling grooves 27, 27' via upstream side to the flow passage 8.
