摘要： A rotating pump includes an outer rotor and an inner rotor. The inner and outer rotors are rotated by a drive shaft between a first side plate and a second side plate to pump put fluid. The first side plate faces the inner and outer rotors and has a first surface and a second surface. The first surface is inclined to an axial direction of the drive shaft to create a wedge-shaped gap between itself and one of the inner and outer rotor. The second surface extends more parallel to a direction perpendicular to the axis direction of the drive shaft than the first surface does. The geometric configurations of the first and second surfaces serve to minimize the leakage of the brake fluid without sacrificing a reduction in resistance to sliding motion of the inner rotor and the outer rotor on the second side plate.

摘要： A rotary pump has a linear groove formed on an end surface of a second side plate of an outer rotor. Thereby, it becomes possible to generate a force for pushing back the outer rotor to a sealing member side, and thus it becomes possible to reduce load applied to the second side plate. As a result, contact resistance between the outer rotor and the second side plate becomes smaller, and smoother pumping operation becomes possible. Further, since the force for pushing back the outer rotor to the first sealing member side is generated in the linear groove, it is possible to reduce an amount of decrease in a contacting area with the outer rotor and the second side plate, thereby reducing an amount of wear of the outer rotor and the second side plate.

A control unit comprises: a first drive circuit that controls the first pressure-reducing valve; and a second drive circuit that is separate from the first drive circuit and that controls the second pressure-reducing valve.

摘要： A braking apparatus for a vehicle is provided which includes a hydraulic booster to make wheels of the vehicle produce frictional braking force, a solenoid valve, and a collision avoidance controller. The solenoid valve selectively exerts the hydraulic pressure of brake fluid stored in an accumulator on a spool valve in the booster. When determining that there is a risk of a collision with an obstacle, the collision avoidance controller opens the solenoid valve to achieve emergency braking to minimize the risk of the collision. Basically, emergency braking is achieved by installing the solenoid valve to selectively exert the hydraulic pressure on the spool valve, thus allowing an emergency avoidance braking system to be constructed with a minimum of equipment and facilitating the mountability of the braking apparatus in the vehicles.

摘要： An electric braking device includes: a first valve unit for adjusting a first differential pressure between a master cylinder side liquid pressure and a wheel cylinder side liquid pressure; a storage unit forming a fluid storage chamber; second valve units for adjusting a second differential pressure between the master cylinder side liquid pressure and a storage chamber side liquid pressure; an electric pump for discharging the fluid in the storage chamber; and a control unit which, while operating the electric pump during a time from initiation of braking force application until a request value acquired by a request braking force acquiring unit reaches a maximum value, controls the first valve unit such that the first differential pressure becomes zero, and controls the second valve units such that the second differential pressure becomes zero.

摘要： A rotary pump includes a first side plate and a second side plate between which an outer rotor and an inner rotor are arranged. The second side plate has a concave portion on a surface adjacent to a maximum gap portion relative to a drive shaft. The concave portion is located in an outer teeth passing section which is defined between a line on which a teeth tip of an outer teeth part of the inner rotor passes in response to rotation of the inner rotor and a line on which a teeth bottom of the outer teeth part of the inner rotor passes in response to rotation of the inner rotor. The concave portion communicates with one of a plurality of gap portions while the inner rotor is rotated.
