A door closer capable of adjusting door closing speed, includes a pneumatic cylinder on the door frame, a hydraulic cylinder on the door, and a lever. One end of the lever is movably connected to the pneumatic cylinder, and the other end is connected to the hydraulic cylinder. The pneumatic cylinder includes a sliding rail, and a sliding member cooperated with the sliding rail. A hermetic chamber is formed by the sliding member and the sliding rail. An adjusting valve, for adjusting the air exhaust of the hermetic chamber, is provided on a wall of the hermetic chamber.

In a lid device opening and closing a fuel lid of a vehicle by a push-push mechanism, a common push lifter can be applied in both cases with and without a mechanism for locking the fuel lid at a closed position. The lid device (20) indirectly locks the fuel lid (10) at the closed position by controlling a displacement of a push rod (22) protruding and retracting from a push lifter unit (24). In order to control the displacement of the push rod (22), an engagement member (56) engaging the push rod (22) is movably supported in a housing (54) of a drive unit (26), and the push lifter (24) and the drive unit (26) are formed as separate members.

A door closer or operator includes a pivoting pinion on the door closer housing for transmitting door motion, and a cam connected thereto. A connecting member extends along a spring and engages the peripheral edge of the cam. Rotation of the cam causes a change in length of the portion of the connecting member between the position tangent to the cam peripheral edge and the spring second end to expand or compress the spring, resulting in a force transmitted along a longitudinal axis of the connecting member as a result of spring deflection. The cam peripheral edge has a profile with a varying radial distance between the cam axis and the connecting member at the position tangent to the cam peripheral edge such that the radial distance is changed as the spring expands or compresses to maintain a desired constant torque about the axis of the cam and pinion.

A closing device pivots on a vehicle body between a closing position and an opening position, such as a rear flap of a motor vehicle, with a closing element on the body side and an opposite closing element on the flap side for locking and unlocking the flap and with at least one ejection element. A plunger can be moved in a guide at least between a working position and a rest position, which upon movement into a working position can be tensioned against the force of a tensioning device. The plunger interacts with the flap for the manual opening and closing through the at least partial relaxing of the plunger. The plunger is lockable and unlockable through a locking device in a locking position in which it is tensioned at least as far as to the working position.

The present invention provides a drive mechanism for a vehicle lift gate. The drive mechanism includes a housing including a first end securable to a vehicle frame and an opposite second end securable to a lift gate. The drive mechanism further includes a spring disposed for movement within the housing along the axis between the first and second ends and biasing the first end axially relative to the second end. A damper extends around the housing for absorbing energy released by rapid axial movement of the spring relative to the housing.

A method of installing a replacement door closer assembly including a closer mechanism includes the steps of: (a) removing a previous door closer assembly from a mounting surface of a door or a door jamb; (b) fixing a first mounting bracket on the mounting surface through a first pre-existing mounting hole; (c) extending the closer mechanism of the replacement door closer assembly through the first mounting bracket while aligning a second mounting bracket with at least a second pre-existing mounting hole in the mounting surface; (d) sliding the closer mechanism back toward the first mounting bracket so that the second mounting bracket can be fixed to the mounting surface through the second pre-existing mounting hole; and (e) positioning and securing the closer mechanism between the first and second mounting brackets.

Disclosed is a door closer provided with a unit for adding door-closing force inside a housing. The disclosed door closer comprises a force-adding unit, which is included inside the housing, for adding the door-closing force. The force-adding unit comprises a cam which coaxially rotates with a link shaft inside the housing, and a cam pusher which is elastically compressed so as to come into close contact with the outer circumferential surface of the cam. The outer circumferential surface of the cam comprises an arc surface portion which is separated apart from a rotary axis of the cam at an equal distance, a concave surface portion which is separated apart from the rotary axis of the cam at a distance shorter than that to the arc surface portion, and one pair of protruding corner portions for connecting the arc surface portion and the concave surface portion. When the outer circumferential surface of the cam with which the cam pusher comes into close contact is converted from the arc surface portion to the concave surface portion due to the rotation of the cam, the rotational force of the link shaft is increased due to the elastic pressing force of the cam pusher.
