  • Patent number: 11346259
    Abstract: A device for controlling a camshaft phaser includes a hydraulic element with a body, a slide assembly having a slide body, and a valve assembly with a first valve, a second valve, and a third valve. The device also includes an actuator which moves along a longitudinal axis between 1) a first position in which the first valve opens or closes a first fluid communication, 2) a second position in which the second valve and the tray open or close a second fluid communication, and 3) a third position in which the third valve and the slide body open or close a third fluid communication between a retard port and a retard chamber.

  • Patent number: 10358953
    Abstract: A valve for restricting flow through an opening of a control valve in a vehicle engine includes a tubular shell having a central axis that extends between open ends of the shell. The shell also includes a base and a blocking element having an interior surface exposed to an internal space of the shell and an exterior surface exposed to an exterior space surrounding the shell. The blocking element is connected to the base by a deflectable connector such that the blocking element can be deflected towards the central axis in response to fluid pressure acting on the exterior surface, and away from the central axis in response to fluid pressure acting on the interior surface so as to selectively block the opening.

  • Patent number: 9376939
    Abstract: An internal combustion includes a crankshaft and a camshaft rotatable by the crankshaft. The internal combustion engine also includes an oil source, an engine cover, and a drive member disposed within the engine cover for transferring rotational motion from the crankshaft to the camshaft. A camshaft phaser actuated by an electric motor is disposed within the engine cover for controllably varying the phase relationship between the crankshaft and the camshaft. A supply passage communicates oil from the oil source to the camshaft phaser in order to lubricate the camshaft phaser and a drain passage drains oil from the camshaft phaser to the oil source. A sealing arrangement defines a dry zone within the engine cover to isolate the drive member from oil used to lubricate the camshaft phaser. The sealing arrangement includes an electric motor to camshaft phaser seal to seal between the electric motor and the camshaft phaser.
