    摘要: A recess hole is connected to a radially outer side of an oil passage portion and forms an oil supply passage. A check valve part has: a valve seat portion provided in the oil passage portion to form a valve seat; a sleeve having one end connected to the valve seat portion; a lateral hole to communicate an internal space of the sleeve with outside of the sleeve; and a valve body provided in the sleeve so as to be separated from the valve seat or in contact with the valve seat. The lateral hole has an opening exposed to outside of the sleeve, and a range of the opening overlaps with a range of the recess hole in an axial direction of the sleeve.

    摘要: A camshaft adjuster (1) is provided, including a drive element (2) and a driven element (3), which can be rotated in relation to the drive element within an angular range and can be connected to a camshaft, wherein pressurizable working chambers (4) for rotating the drive element (2) with respect to the driven element (3) are formed between the drive element (2) and the driven element (3), wherein the camshaft adjuster (1) has a volume accumulator (5) for collecting hydraulic medium, wherein the volume accumulator (5) supplies the hydraulic medium to a vacuum-pressurized working chamber (4) via a check valve (6) in that the vacuum in the working chamber (4) opens the check valve (6), characterized in that the check valve (6) is arranged in an axial position between the working chamber (4) and the volume accumulator (5), and the volume accumulator (5) is formed by a cover element (7) connected to the drive element (2) for conjoint rotation.

    摘要: 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.

    摘要: A camshaft phaser includes an input member; an output member defining an advance chamber and a retard chamber with the input member; a camshaft phaser attachment bolt which clamps the camshaft phaser to a camshaft, the camshaft phaser attachment bolt having a bolt valve bore extending along an axis. A valve sleeve is located coaxially within the bolt valve bore such that an annular clearance is provided radially therebetween. A valve spool is located coaxially within the valve sleeve such that the valve spool is moved coaxially between an advance position and a retard position. A compliant sealing ring radially between the bolt valve bore and the valve sleeve prevents fluid communication through the annular clearance axially between opposing axial sides of the sealing ring and isolates the valve sleeve from radial expansion of the camshaft phaser attachment bolt.
