  • Patent number: 10072538
    Abstract: A cam shaft phase setter for adjusting the rotational angular position of a cam shaft relative to a crankshaft of an internal combustion engine by a hydraulic fluid, the cam shaft phase setter including: a stator connected to the crankshaft; a pressure chamber; a rotor connected to the cam shaft, the rotor being adjustable relative to the stator by introducing the fluid into the pressure chamber; a control valve including a valve housing and a valve piston; and an actuating unit for axially adjusting the valve piston; wherein the cam shaft phase setter is configured such that fluid flowing through the control valve flows back into an engine housing which rotatably mounts the cam shaft.

  • Patent number: 9970333
    Abstract: A cam shaft phase setter for adjusting the rotational angular position of a cam shaft relative to a crankshaft of an internal combustion engine by means of a hydraulic fluid, the cam shaft phase setter including a stator which can be rotary-driven by the crankshaft; a pressure chamber for the fluid; a rotor which is connected, rotationally fixed, to the cam shaft and coupled to the stator such that torque is transmitted and which can be adjusted in its rotational angle relative to the stator by introducing the fluid into the pressure chamber; a control valve including a valve housing and a valve piston; the valve housing including a housing inlet, an operating port to the pressure chamber and a reservoir port to a reservoir for the fluid and being connected, rotationally fixed, to the cam shaft or being formed by the cam shaft; the valve piston being axially adjustable back and forth in the valve housing between a first position and a second position and including a piston feed which is connected to the housi

  • Patent number: 9021997
    Abstract: A cam shaft phase setter including a control valve for controlling the feeding and draining of a hydraulic fluid into and out of a pressure chamber which serves to adjust the rotational angular position of a cam shaft relative to a crankshaft of an internal combustion engine. The control valve includes a valve housing with an operating port to the pressure chamber and a reservoir port to a reservoir for the fluid. A valve piston is axially adjustable back and forth in the valve housing between a first position and a second position and includes an axial hollow space, a piston inlet for introducing the fluid into the hollow space, and a piston outlet which leads out of the hollow space and is connected to the operating port in the first position of the valve piston and separated from the operating port in the second position of the valve piston. An actuating unit is coupled to the valve piston for axially adjusting the valve piston.
