摘要： A linear actuator includes a jacket defining an axis, and a rod having an end cylinder tightly slidable within the jacket and an opposite end sliding between a rest position and a working position. The end cylinder divides the jacket into a first and second variable volume compartment fluidically independent from each other, one of the first or second variable volume compartment being fluidically insulated and under vacuum, the other one fluidly communicating with the outside environment. The jacket has an abutment member having a non-return valve mechanism adapted to discharge ambient air that may be entrapped between the end cylinder and the abutment member.

摘要： A hood lifting assembly according to various implementations includes a re-latching feature that allows two slidably coupled plates to be reset, or locked, relative to each other by moving a head of a pin into a keyhole opening of a keyhole slot defined in one of the plates. In an initial position, the head of the pin is spaced apart from the keyhole opening, allowing the pin to move along the keyhole slot from the initial position to a deployed position and then to a reset position. In other implementations, a hood lifting assembly includes an energy absorbing feature. One exemplary energy absorbing feature includes a plate defining an elongated slot that has a narrowed width portion through which a pin travels during movement from the initial position to the deployed position.

摘要： A scupper door system includes a frame defining a passageway. A door is mounted within the frame at a pivot and is therein rotatable about the pivot within the passageway between a closed position, blocking the passageway, and an open position wherein the passageway is open to permit passage of water therethrough. A latch mechanism is configured to retain the door in the closed position and is triggerable in response to a preset water condition at one side of the passage to release the door from the closed position and allow the door to rotate to the open position.

摘要： A control system for a power assisted door, the electronic door control system includes an intelligent control, a plurality of sensor inputs operatively connected to the intelligent control, the plurality of sensor inputs associated with state of a plurality of mechanical components of the power assisted door, and a power drive operatively connected to the intelligent control for providing opening and closing of the power assisted door. The intelligent control is configured to monitor status of the plurality of sensor inputs and control the power drive at least partially based on the status of the plurality of sensor inputs. The intelligent control may be adapted to determine when state of the plurality of sensor inputs is indicative of one or more conditions which would preclude safe door movement. A power distribution module may also be present to assist in limiting current draw and to allow for charging.

摘要： Rotary drive, particularly for vehicle doors, in which the piston motion of a piston-power cylinder-unit 5 is converted into a rotary motion by means of roller pairs 14 which engage into oblique slots 10, 11. The oblique slots are provided in cylinders 4, 6 arranged coaxially inside each other and one of the cylinders is connected to the power output shaft 7. The slots exhibit an axial direction at their ends. Herein the cover 2 of a pot-shaped housing 1, through which cover the power output shaft 7 passes, exhibits a collar 15 projecting outwards and embracing the power output shaft. The power output shaft 7 is provided with a cup-type seal 17 seated firmly upon it, whose surface contour 18 overlaps outwardly the collar 15 and which with its edge 19 rests tightly at the cover 2. The cover is provided with an axially oriented groove 20 on its side facing away from the collar, into which groove the edge of the pot-shaped housing 1 is tightly fitted.

摘要： A hydraulic drive for a sash of a door, a gate, a window or the like comprises a housing and a piston which is displaceably guided in the housing and which divides the interior of the housing into a pressure chamber and a non-pressurized chamber. In this case, the drive, which can in particular be a hydraulic door closer, comprises a regulating valve which is arranged on the end face of the housing delimiting the pressure chamber on the side facing away from the piston and which is integrated in particular in a housing cover for activating an impact function. The regulating valve has a valve member which is displaceable between a closed position and an open position in a valve bore of a valve housing formed in particular by the housing cover, is impinged on in the closing direction by the pressure in the pressure chamber and can be transferred into the open position thereof by the spring force of a spring unit when the pressure in the pressure chamber falls below a predeterminable limit pressure.

摘要： A door driving device includes a driving unit driving a door that opens and closes an entrance of a vehicle having a door case, and a control unit controlling the driving unit such that the door moves with a discontinuous acceleration during a period from when the door starts to open to when the door moves at a constant speed in an opening direction in which the door is retracted into the door case.
