A pump for anti-lock brake systems which is constructed so that a piston (40), an inlet check valve (100), and an outlet check valve (200) are integrally assembled with each other and are mounted in a bore (3), thus enhancing an assembling efficiency and b...

The device has an electric motor (1) driving a coaxial pump (2), a universal joint connection between the motor and pump via a coupling part (6) with a shape-locking plug-in holder for a driven side rotor shaft end (4) of the motor and drive side pump shaf...

A piston pump comprises cylinder attached within a cavity of a pump housing. An outlet check valve seat is defined about an outlet of the cylinder. A piston is slidably received in a bore of the cylinder and has a first passageway formed therein. A cylinde...

The motor-pump unit has an electric motor (1) and a piston pump (2), the drive shaft (4) of the electric motor and the support axis (10) of the pump formed as separate components, with axial forces transmitted to the support axis via a triple ring bearing ...

A pump device comprising a support member (82; 220; 288; 328; 406, 408; 450; 502) having a fitting recess, a movable member (80; 276; 322; 402, 404; 514) which is reciprocated in said fitting recess to suck a working fluid, pressurize the fluid and deliver...
