Abstract: When a first and a second reservoirs are disposed at positions below a central axis of pumps and are offset from a center portion in a lateral direction of a housing when viewed from a front surface side, outer peripheral sides of a first and a second reservoir usually become dead spaces. Therefore, first and second wheel pressure sensors are disposed in the dead spaces.

Abstract: A reservoir container has a reservoir, and a communicating passage that guides brake fluid to the reservoir. The reservoir of the reservoir container that accumulate the brake fluid is made to a hole extending in a transverse direction so that a size of the reservoir container in a height direction is made small while fully securing the capacity of the reservoir. Moreover, a horizontal plane projected area of the communicating passage is made smaller than that of the reservoir, so that a sealing part of the communicating passage is shortened, and ensures the seal integrity.

Abstract: A motor, installed on a first surface of a housing, has a drive shaft normal to the first surface. Two pumps are installed in the housing and driven by the motor for introducing and discharging operation fluid. Two reservoirs are provided in the housing for storing the operation fluid released from a wheel cylinder and supplied to the pump. Each reservoir has an opening at a second surface of the housing and an axis normal to the second surface. Two dampers are provided in the housing for suppressing pulsation flow of the operation fluid discharged from the pump. Each damper has an opening at a third surface of the housing and an axis normal to the third surface. The third surface faces to the second surface so that the drive shaft of the motor is interposed between the second surface and the third surface.

Abstract: A valve timing adjuster according to the present invention, comprises a pulley rotationally connected to one of an output shaft of engine and a cam shaft, a sleeve which is supported on the pulley, which is rotatable within a predetermined angle of rotation on the pulley and which is rotationally connected to the other one of the output shaft of engine and the cam shaft, an electromagnet mounted on one of the pulley and the sleeve, an armature mounted on the other one of the pulley and the sleeve so that magnetic flux including a magnetic flux component extending in the circumferential direction of the valve timing adjuster is generated, the armature is drawn by the magnetic flux toward the electromagnet and the sleeve is rotated within the predetermined angle of rotation on the pulley when the electromagnet is energized, and a control device which controls the operation of electromagnet so that the phase difference between the cam shaft and the output shaft is suitably adjusted during operation of a vehicle.
