Abstract: For improving manual operation of an actuator (1), a novel clutch (4, 6) is proposed that features at least one movable protrusion (12) that is axially movable along a coupling axis (11) of the clutch (4, 6) relative to an element (8) that carries the protrusion (12). This design has the advantage that engagement of the clutch (4, 6) is possible under all circumstances, even in cases in which the protrusion (12) is not yet in a correct rotational coupling position (18) (cf. FIG. 7), as the protrusion (12) can be transferred into the coupling position (18) by a rotational movement (24, 25) at all times.

Abstract: A clutch mechanism that can be used in various tools and mechanisms for holding a movable shaft in one or more preferred positions includes a clutch ring that surrounds the shaft. An interior diameter of the clutch ring is configured to closely surround and grasp one or more holding portions of the shaft.

The clutch ring can take the form of a generally cylindrical sidewall. Openings may be formed through a thickness of the cylindrical sidewall to make it easier for portions of the clutch ring to elastically deform, thereby allowing the shaft to move relative to the clutch ring.

Abstract: A hydraulic assembly with a lubricant output, a control output and a pump which can supply a hydraulic fluid flow to the lubricant output and the control output. A switching valve with structurally predefined hysteresis is arranged between a pump output and the control output of the hydraulic assembly. Depending on the pressure in the branch between the pump output and the control output, the valve can be switched between an open position in which the control output is connected to the pump output, and a blocking position in which the control output is blocked off. The switching valve switches from the open position to the blocking position when the pressure provided by the pump exceeds an upper switching threshold, and returns from the blocking position to the open position when the pressure provided by the pump falls below a lower switching threshold. A clutch can be switched by means of such a hydraulic assembly, and a method for actuating the clutch.
