An operator assembly may move a window vent relative to a frame. The operator assembly includes a stationary member, an arm and a drive member. The arm is mounted for rotation relative to the stationary member between an open position and a closed position. The drive member is received in a channel defined by the stationary member for linear motion therein relative to the stationary member and the arm among a first position in which the drive member engages a locking feature of the window vent, a second position in which the drive member is spaced apart from and disengaged from the locking feature without rotating the arm out of the closed position, and a third position in which the drive member is further spaced apart from the locking feature. Movement of the drive member between the second and third positions moves the arm between the closed and open positions.

A rack-and-pinion steering for a motor vehicle, having a rack which has a longitudinal axis, a rack housing in which the rack is guided for axial displacement, and at least one end stop damping assembly for the rack, the end stop damping assembly being received in the rack housing, the end stop damping assembly including a compression body for damping an end stop and a stop member which is mounted to the rack housing for limited displacement in the axial direction, the stop member resting against a first supporting surface of the rack housing at least partly by means of the compression body in a first axial direction and resting against a second supporting surface of the rack housing in an opposite, second axial direction.

An injector for ejecting an intraocular lens into an eye, comprises a longitudinal injector body, in which an injector piston rod can be guided in an axially displaceable manner, an injector nozzle at a front end of the injector body, in the direction of which the injector piston rod can be displaced, a displacement mechanism for pushing the injector piston rod forwards, and an actuating element for the manual actuation of the displacement mechanism.

The displacement mechanism includes a transmission mechanism, by means of which the actuating element and the injector piston rod can be placed in an articulated driving connection, and an operating region for the actuation of the actuating element is formed at a longitudinal side of the injector body.

A steering system includes a rack housing in which a rack shaft is housed, rack ends fitted to respective end portions of the rack shaft and coupled to respective steered wheels, and shock-absorbing members provided between the rack housing and the respective rack ends. When the rack shaft moves in a direction in which an end face of the rack end approaches a restricting surface of the rack housing and thus the rack shaft reaches a position after the shock-absorbing member is compressed by a compression amount, a control unit creates a normal input end through electronic stopper control of reducing an assisting force to be generated by a motor. This restricts movement of the rack shaft in a direction in which the end face approaches the restricting surface.

One embodiment of the present invention provides an actuator comprising: a housing having a mounting space part formed therein; a motor part provided inside the housing and generating power; a reduction gear part of which a plurality of gears respectively having an internal gear and an external gear sequentially engage with each other so as to transmit the power generated in the motor part; and a rod part engaging with the gear disposed at the last position, and linearly moving according to the rotation of the gear, wherein one of the plurality of gears is formed such that the internal gear and the external gear can rotate together or rotate independently.

An assembly, including a first chamber (1) and at least one second chamber (2) and at least one pivoting drive (3) for pivoting a pivoting object (4) of the assembly, wherein the pivoting object (4) is arranged in the first chamber (1) and at least one intermediate wall (5) is arranged between the first chamber (1) and the second chamber (2). A transmission body (6), which is annular at least in some sections, can be rotated about an axis of rotation (7) by the pivoting drive (3) and is fed through at least one feed-through opening (8), preferably two feed-through openings (8), in the intermediate wall (5).

A rack-and-pinion gear is described, which is suitable in particular for a steering system of a motor vehicle. In this a pinion is supported in a pinion housing and meshes with a rack inside this pinion housing. The rack here projects from the pinion housing through at least one housing aperture. A stop ring, which serves to limit a rack longitudinal movement and/or a tilting of the rack, is moreover held in the housing aperture by means of a press fit. In addition, a steering gear having such a rack-and-pinion gear and a steering system for a motor vehicle comprising such a steering gear are described.

An electronic device includes a machine body, a functional module, a power transmission module and a retracting module. The functional module is to move with respect to the machine body. The power transmission module, disposed in the machine body, includes a transmission unit and a driving unit. The transmission unit includes a gear and a rack. The driving unit, connected to the gear, is to move with the functional module. The driving unit rotates the gear in a moving direction to mesh the rack so as to move the functional module in the moving direction. The retracting module, disposed in the machine body, includes a holding unit connected to the rack to provide the rack an avoiding path for the rack to disengage the gear, and a direction of the avoiding path is different from the moving direction. In additional, a camera device is also provided.

The disclosure relates to an apparatus for pressing a toothed rack against a pinion, having a pressure piece. The pressure piece can be arranged so as to be displaceable inside a housing and in an axial direction of a centre longitudinal axis. A bearing element that can be fixed on the housing in an axial direction with respect to the centre longitudinal axis, having a prestressing element that acts in an axial direction. Action of the prestressing element arranged between the bearing element and the pressure piece subjected the pressure piece to a prestressing force in an axial direction with respect to the centre longitudinal axis and directed away from the bearing element. A sliding element is arranged on a side, facing away from the prestressing element, of the pressure piece for the purpose of bearing against the toothed rack. In order to reduce the production outlay and/or allow a more compact design, on the side bearing against the sliding element, the pressure piece has a contour for compensating tolerances. The contour interacts with the sliding element.
