An actuator comprising a housing, a piston driven member axially movable within the housing and being coupled to the housing by a first pin and ramp coupling such that axial movement of the piston driven member relative to the housing is accompanied by angular movement of the piston driven member relative to the housing. The actuator includes an output member constrained against axial movement relative to the housing and coupled to the piston driven member by a second pin and ramp coupling such that both axial and angular movement of the piston driven member drive the output member for angular movement relative to the housing.

The present invention relates to a cam-operated device (5) for controlling at least one component, said device comprising a cam (6) comprising at least one first camway (7, 8) on a first face and a second camway (9) on an opposite face, said first camway (7, 8) having a depth, measured starting from an opening, at the level of said first face, of said first camway, and said second camway (9) having a depth, measured starting from an opening, at the level of said opposite face, of said second camway, a height of the cam (6), measured between the opening of the first and second camways, being less than the sum of the depths of the camways (7, 8, 9).

An adaptor for a powered surgical instrument includes a casing, a cam drum, a first linear driver, and a second linear driver. The cam drum defines and is translatable along a longitudinal axis of the adaptor between a retracted position and an advanced position. The cam drum is being supported for rotation about the longitudinal axis. The cam drum defines first and second radial cam grooves about an outer surface thereof. The first cam groove defines a first profile and the second cam groove defines a second profile. The first linear driver includes a first cam follower disposed in the first cam groove and the second linear driver includes a second cam follower disposed in the second cam groove. The first and second linear drivers are supported for movement between advanced and retracted positions in response to rotation of the cam drum.

A drive unit for motor vehicle applications, in particular motor vehicle closing devices. The drive unit comprises an electric motor and at least one drive element driven by the electric motor. In addition, an actuation lever that cooperates with the drive element is provided. The drive element and/or the actuation lever are advantageously designed to be able to rotate about an axis. A rotatably mounted intermediate element is provided between the drive element and the actuation lever. According to the invention, the intermediate element is in the form of a friction-reducing rolling element.

Provided is a plate material feeding device that can achieve reduced power consumption, improve durability, and supply plate material with high precision. A plate material feeding device is provided with a housing, a lower roll, an upper roll, a lower roll support member for supporting the lower roll, an upper roll support member for supporting the upper roll, and a slider movable in the horizontal direction along the upper roll support member, and can feed plate material clamped by the lower roll and the upper roll. A hole is provided in the slider, and a rod is provided in the upper roll support member. By inserting at least part of the rod in the hole in a slidable manner, the upper roll support member can move in the vertical direction when the slider moves in the horizontal direction.

A cam device includes a drive cam, a follower, a holding cam, and a restriction roller. The drive cam reciprocally rotates. The follower intermittently reciprocate linearly by the drive cam. The holding cam is rotationally driven integrally with the drive cam. The restriction roller is provided on the follower and restricts a movement of the follower by coming in contact with the holding cam. The holding cam separates from the restriction roller and the holding cam is in a holding release state, when the drive cam is in an engaged state with the follower.

An adjustable stroke mechanism has a housing with a central axis and a wall enclosing a cavity. At least one counterweight is movably disposed within the cavity. A mounting assembly is disposed within the cavity. The mounting assembly has a workpiece attachment mechanism. A stroke adjustor couples the at least one counterweight with the mounting assembly. The stroke adjustor enables the counterweight and mounting assembly to move with respect to one another such that a distance between the counterweight and the mounting assembly is variably adjusted which, in turn, variably adjusts a stroke radius of the workpiece attachment mechanism with respect to the central axis of the housing.
