A number of variations may include an actuator and valve arrangement.

An anti-coking valve arrangement (10) having a valve body (52) that defines a passage for the flow of fluid medium. Valve seat (76) and valve member (66) positioned within the valve body (52) and function to control the flow of fluid medium. A first anti-c...

A method of controlling exhaust gas recirculation by means of an EGR valve (55). An electromagnetic actuator (41) is associated with a housing (47) to transmit movement of an actuator output (75) into reciprocating movement of the EGR valve in response to ...

Particle trapping means (28, 29) for trapping worn particles (20a) of a commutator (14) is provided in a power source side case (15) mounted on a motor case (2) of a DC motor (1).

A method of operating a control system to move an EGR valve (24) toward its seat (32), in which the control system includes an actuator (16) operable in response to an electrical position command signal (84,86). The method comprises the steps of determinin...

The detection of a valve-opening starting position of an exhaust gas recirculation (EGR) valve which is disposed in an exhaust gas recirculation system is surely made, and the amount of movement of a motor shaft of an electric motor in a valve-closing dire...

A DC motor for driving an exhaust gas recirculation valve provided in an exhaust gas recirculation system is controlled by an analog circuit to thereby simplify the circuit configuration and improve the security against a high temperature.
