Abstract
PURPOSE: To actuate a stable brake force at all the times by a method wherein a set pressure of a relief valve setting an oil pressure in a brake chamber is detected and the detected valve is controlled so as to become a predetermined value to be set depending on the operating condition of an engine.
CONSTITUTION: Four sets of oil feeding holes 13, communicating with an oil supplying groove 12 at all times, are formed in a plunger 6 and the oil supplying groove 12 is communicated with an oil feeding chamber 14 through the oil feeding holes 13. A slit 15 is formed into a triangular shape and an opening area thereof is controlled by a flange 9 of a housing 3 when the plunger 6 makes a vertical motions. The opening area of the slit 15 communicating a brake chamber 10 with the oil feeding chamber 14 is limitted by the flange portion 9 and as the plunger 6 is lowered, the opening area of the slit 15 becomes smaller and an oil pressure in the brake chamber 10 is increased, therefore, a reactional force against the descending of the plunger 6 becomes stronger.
