Abstract
PURPOSE: To limit brake oil pressures at a certain valve with no relation with rapid or slow braking operation by using a sensing valve to determine the circulation state of oil from its flow speed, which rushes into a valve case.
CONSTITUTION: A valve case having an inlet and outlet port 2, 3 accomodates a small- and large-diameter cylinder hole 4, 5 and a spring room 6 which contain each of a small- and large-diameter piston 7, 8 and a spring 9, and a valve room 10 divided into a front and rear chamber a, b by a partition plate 15. The front chamber a accomodates a spherical sensing valve 11. The brake oil pressure control valve constituted as mentioned above is assembled in a brake oil pressure circuit that its bottom face 10a inclines at a specified angle, facing to the front of a vehicle. Presurized oil having flown from the inlet port 2 into the valve room 10 through a inflow hole 12 has no effect on the sensing valve 11 at slow flowing and the other hand, at fast flowing, part of the oil running against the inwall of the valve room 10 pushes the sensing valve 11 to close. A brake oil pressure can be limited at a specific value.
