摘要： A control valve includes a valve housing extending along a longitudinal axis. The valve housing defines an inlet port, a first outlet port, and a second outlet port. In addition, the control valve includes a spool guide disposed inside the valve housing and a flow guide belt disposed around the spool guide. The flow guide belt is disposed inside the valve housing. The control valve further includes a spool movably disposed in the spool guide. The spool can move relative to the valve housing along the longitudinal axis between a first spool position and a second spool position. The first outlet port is in fluid communication with the inlet port when spool is disposed in the first spool position.

摘要： A piston for a hydraulic valve of a rotation phaser, wherein the piston is configured hollow cylindrical, wherein the piston is axially movable in a central opening extending along a first longitudinal axis of a housing of the hydraulic valve, wherein operating connections of the housing are opened and closed according to a position of the piston, wherein the piston includes check valves which prevent an unintentional outflow of a hydraulic fluid flowing through the piston from an inner cavity of the piston in flow through openings of the piston associated with the operating connections, wherein the piston is configured with check valves in its inner cavity that open towards its interior cavity, wherein the check valves are fixated by a spacer element that is arranged between the two check valves. The invention also relates to a hydraulic valve for a rotation phaser of a cam shaft.

摘要： In a valve timing adjusting device, a vane rotor includes a second supply oil passage connectable to a first supply oil passage of a second shaft. A check valve is provided between the vane rotor and the second shaft, and permits a flow from the first supply oil passage toward the second supply oil passage and prevents a flow from the second supply oil passage toward the first supply oil passage. A fixing unit is provided between the check valve and the second shaft, and fixes the check valve between the fixing unit and the vane rotor. The fixing unit includes a third supply oil passage which connects the first supply oil passage and the second supply oil passage. A filter is provided for the fixing unit and can capture foreign substances flowing through the third supply oil passage.

摘要： Methods and systems are described for an engine with a cam torque actuated variable cam timing phaser. Phaser positioning control is improved by reducing inaccuracies resulting from inadvertent spool valve and/or phaser movement when the spool valve is commanded between regions. In addition, improved spool valve mapping is used to render phaser commands more consistent and robust.
