摘要： A flow control device or valve used in a power steering system of an automotive vehicle. The flow control device comprises a housing formed with an axially extending hole in which a spool valve is movably disposed. A first pressure chamber is defined in the hole, with one end of the spool valve. A drain passage is opened to the first pressure chamber and closable with the spool valve. A second pressure chamber is defined in the hole, with the other end of the spool valve. A restricting orifice is provided to be communicated with the first pressure chamber. An introduction passage is formed to be communicated through the restricting orifice with a discharge passage and opened to the first pressure chamber. The pressure in the discharge passage is introduced to the second pressure chamber. A first spring is disposed in the second pressure chamber to bias the spool valve in a direction to close the drain passage. A spring holding member is movably and coaxially disposed in the axially extending hole. The spring holding member has a first end face defining the second pressure chamber, and a second end face which is larger in pressure-receiving area than the first end face. The first spring is disposed between the spool valve and the first end face of the spring holding member. The second end face of the spring holding member defines a pressure control chamber communicated with the second pressure chamber. Additionally, a second spring is provided to bias the spring holding member in a direction to reduce a volume of the pressure control chamber.

摘要： A power assisted steering apparatus for a vehicle having a driving source, such as an engine, has an actuator, a hydraulic pump, a working oil pressure passage, and a drive switch. The actuator, which is in the vehicle steering mechanism, receives a supply or exhaust of a working oil to assist the steering operation. The pump is selectively driven by an engine via a clutch mechanism. The working oil discharged from the pump is introduced into the actuator via the passage. The check valve is interposed within the passage to enable flow in one direction away from the pump. The drive switch structure is disposed within the passage, downstream from the check valve. With this arrangement, the drive switch structure can be activated by pressure in the passage downstream of the check valve to control the clutch mechanism.

摘要： In a brake control apparatus, a fluid passage section is hydraulically connected between a hydraulic pressure source and a wheel cylinder. A first pressure sensor measures a first quantity correlated to a hydraulic pressure outputted by the hydraulic pressure source. A second pressure sensor measures a second quantity correlated to an internal pressure of the wheel cylinder. A controller controls a braking force of a wheel by the wheel cylinder. The controller is configured to: allow the first pressure sensor to obtain a value of the first quantity, and allow the second pressure sensor to obtain a value of the second quantity, while allowing a selector to regulate fluid communication between the hydraulic pressure source and the wheel cylinder; and calibrate the first and second pressure sensors with respect to each other in accordance with the obtained values of the first and second quantities.
