Abstract: A cam shaft adjuster for adjusting the angle-of-rotation positions of a cam shaft relative to a crankshaft. The cam shaft adjuster has at least two operating chambers to which pressure oil can be supplied to change the angle-of-rotation position. At least one of the operating chambers can be deactivated depending on an operating parameter by blocking the pressure oil supply.

Abstract: A device for changing the control times of gas-exchange valves in an internal combustion engine is provided, which includes a drive wheel (2) in driven connection with the crankshaft and a vane rotor (3) fixed with the camshaft. The drive wheel (2) has a hollow space, which is formed by a hollow cylindrical peripheral wall (4) and two lateral walls (5, 6), in which at least one hydraulic work chamber (9) is formed by at least two radial limit walls (7, 8), which is divided by at least one vane (11) into an A pressure chamber (12) and a B pressure chamber (13). The vane rotor (3) can be coupled mechanically with the drive wheel (2) by a separate locking element (14), that can be moved into a locked position within a receptacle (19) in the lateral walls (5) of the drive wheel (2). The receptacle (19) is connected hydraulically to the A pressure chamber (12) via a pressure medium supply groove (18) provided in an inner surface of the lateral wall (5), so that upon pressurization of the A pressure chamber (12), the locking element (14) can move hydraulically into an unlocked position in the rotor hub (10) of the vane rotor (3). According to the invention, a local stop (20) is arranged within the pressure medium supply groove (18) in the inner surface of the lateral wall (5), through which a pressure medium supply to the receptacle (19) of the locking element (14) is possible only through a bypass (21) when the vane rotor (3) is in the base position.

Abstract: A cylinder and piston unit, which can be utilized to select the gears of and/or to shift a change-speed transmission in the power train of a motor vehicle, has a housing provided with two internal chambers and internal stops and receiving a reciprocable assembly of three pistons including two interconnected pistons each adjacent a different one of the two chambers and a hollow cylindrical piston which surrounds one of the two interconnected pistons. The chambers can receive a pressurized hydraulic or pneumatic fluid jointly or independently of each other to thus effect movements of the interconnected pistons (with and/or relative to the holow piston) against selected stops and to thus select the positions of the interconnected pistons. Such interconnected pistons can be utilized to select the ratio of the change-speed transmission. The chambers can confine springs which assist or oppose the action of fluid upon the surfaces of the interconnected pistons.
