摘要： A pump used in vehicle controlled braking systems provides a reverse direction of flow through a cylinder bore of the pump and utilizes an inlet check valve located outside of the piston at the end of the cylinder bore opposite the piston, in conjunction with an outlet check valve located in an outlet extending through a sidewall of the cylinder bore of the pump. The inlet check valve is assembled and tested as a module prior to being installed in the pump. A fluid reservoir, having a movable wall, is connected to the inlet to facilitate priming the pump module. The piston is driven by a self-supporting drive apparatus with an eccentric element affixed to a stub shaft, or by other forms of a drive apparatus having an eccentric element fixed to a motor drive shaft.

摘要： A hybrid brake apparatus for a vehicle includes a front hydraulically actuated brake circuit, a rear electrically actuated brake circuit, and a controller. The front hydraulically actuated brake circuit includes a master cylinder for providing pressurized fluid to the front brake circuit in response to an input applied to the master cylinder for applying a frictional front braking force. The rear electrically actuated brake circuit is controllable in response to the input for providing a frictional rear braking force. The rear brake circuit is controlled in accordance with a first predetermined relationship between the input and rear braking force during normal operation of the front brake circuit. If the controller detects a degradation of front braking force, the rear brake circuit is controlled in accordance with a second predetermined relationship between the input and the rear braking force, to thereby compensate for the degradation of front braking force.

The pumping assembly is reciprocally driven by the rotatable piston bearing surface along an axis radially disposed from and otherwise parallel to the axis of rotation of the rotatable piston bearing surface. Each of the wobble plates includes an apex that can be rotationally offset relative to the other about the axis of rotation ‘A’ to control the timing of the output cycle of the pumping assemblies; thereby reducing or eliminating the natural harmonic vibrations of the pumping assemblies and/or minimizing the current draw of the motor.
