Brake oil pressure controlling apparatus fof car

Abstract

Abstract PURPOSE: To prevent the early operation of a ball valve by arranging a throttle passage having a small diameter hole formed in parallel to the axis line which passes through the centers of the ball valve and of the valve hole and having a large diamter hole formed on the upper stream side of the small diameter hole, on the upper part of the depart part plate on the upper stream side of the valve chamber. CONSTITUTION: A throttle passage 23 is formed at the upper part of a depart plate 18. Said throttle passage 23 has a small diameter hole on a ball valve 2 side, in parallel to the center axis line which passes through the centers of the ball valve 2 and of a valve hole 9, and on the vacant place 28 side, a large diameter hole is formed which communicates to the small diameter hole, bent at an angle of 30° against the small diameter hole so as to be close to the center axis line. As a result of the formation of the throttle passage, the small diameter hole acts to decide the direction of flow of braking oil, and prevents the dynamic pressure due to flow from being applied to the ball valve 2, and the trouble for the variation of viscosity due to temperature difference can be suppressed to the minimum, and a proper braking action can be applied to a rear brake.
