Abstract: A synthetic material clamp includes a band bent ring-shaped, having band ends with toothed coupling sections together forming a latching coupling. Each coupling section has a first latching element with a latching tooth directed toward a band inner side and a second latching element with a latching tooth directed toward a band outer side. The latching elements are arranged on the coupling sections so the first latching element of a coupling section engages upon closing of the latching coupling. The first and second latching elements are located on opposite sides of a plane centrally dividing the band in a longitudinal direction. The latching elements of both coupling sections include on a side facing the plane a supporting surface arranged when the latching coupling is closed, with the supporting surfaces of one of the latching elements engaging the supporting surfaces of the latching elements of the other coupling section.

Abstract: A device for electromagnetic actuation of a charge change valve for internal combustion engines has an actuator unit that cooperates with the charge change valve and is arranged in a cylinder head of the engine. The actuator has an armature and two switch magnets located on either side of the armature, with the switch magnets holding the charge change valve in an open or closed position. The actuator unit is mounted to float in the cylinder head, with a play-compensating device with a play-compensating piston having a first and second pressure chambers being provided on or in the side of the actuator unit facing away from the charge change valve. The first pressure chamber is controlled as a function of engine pressure and the second pressure chamber is connected by a check valve with the first pressure chamber. Pressure medium can be drained from the second pressure chamber through a throttle line between the play-compensating piston and a cylinder surrounding said piston.
