Abstract: A coupling element for fitting to a threaded spindle. The coupling element has a receiving portion which is formed integrally with a coupling portion. The receiving portion extends in a hollow-cylindrical manner along an axis having an axial receiving opening for receiving the threaded spindle, and the coupling portion is flattened transversely with respect to the axis relative to the receiving portion and has a connection means. In order to be able to produce a coupling element in a more efficient and flexible manner, the receiving portion and the coupling portion be formed from a continuous integral pipe portion, wherein the coupling portion has a pressing portion in which the pipe portion is plastically compressed flat transversely relative to the axis.

Abstract: Linear drive with a gear housing extending along a longitudinal axis, in which a spindle is rotatably mounted with a worm wheel connected to it in a rotationally fixed manner, a spindle nut running on the spindle, which is adjustable on the spindle between a retracted position and an extended position and which acts on a lifting tube. The spindle nut is arranged in the retracted position guide tube and retracted in the region of a rear end of the guide tube, and thus the lifting tube is also retracted into the guide tube. The spindle nut is arranged at a front end of the guide tube in the extended position. An electric motor drives the screw, which extends along a transverse axis extending transversely to the longitudinal axis, wherein the electric motor is accommodated in a motor housing which is connected to the gear housing. Furthermore, a control system is arranged in a control housing. In order to simplify the assembly of the control housing, a connection is formed between the control housing and the drive housing, which is designed in such a way that the latter is simultaneously electrically connected to the drive housing during the mechanical attachment.

Abstract: A linear drive having a transmission housing and an electric motor which is accommodated in the transmission housing and drives a shaft with a worm. The shaft meshes with a worm gear which is non-rotatably connectable to a clutch to a spindle holder non-rotatably connected to a spindle. The clutch is biased by a spring and is adjustable by a clutch actuation. The clutch actuation includes a slide element which bears against the clutch and which is arranged non-rotatably but axially displaceably. A rotary element which is axially fixed but rotatable about an axis of rotation engages the slide element at an outside that faces away from the clutch. Run-on bevels of complementary configuration are provided between the slide element and the rotary element. The rotary element is actuable by a pulling element, and the slide element is axially displaceably in relation to the rotary element.

Abstract: A regulating valve having anti-seize characteristics provides a linear drive system intermediate a drive shaft connected to a motor and a lifter connected to the regulator spring. The linear drive system translates the rotational motion of the drive shaft into preferably, linear only motion of the lifter, thereby preventing binding internal to the valve.

Abstract: Linear actuator (8) comprising a quick release (27) for disengagement of an adjustment element (23) from an electric motor (19) and the part of a transmission (20) extending from the electric motor (19) to the quick release (27), such that the spindle (21) of the linear actuator is rotated under the load on the adjustment element (23). Further, the linear actuator comprises brake means (28) connected to the spindle (21) for controlling the speed of the adjustment element (23), when the quick release (27) is activated. A coupling (34;52,53,54) connected the brake means (28) is configured to set the brake means (28) in an active state, when the coupling (34; 52,53,54) is engaged, or in an inactive state, when the coupling (34;52,53,54) is slipping or disengaged.
