  • Patent number: 11851935
    Abstract: A door opener capable of controlling the door closing speed includes a driving device and a generator mode operating module electrically connected to the driving device. The driving device includes a motor which can be supplied with power to pivot a door from an open position to a closed position. The driving device detects the position of the door by a switch. When pivotal movement of the door is achieved without supplying power to the door, the pivotal movement sets the generator mode operating module to a generator mode or a non-generator mode. In the generator mode, the motor is impeded by the electromagnetic resistance, such that the pivoting speed of the door is reduced. In the non-generator mode, the motor is not impeded by the electromagnetic resistance, such that the pivoting speed of the door is increased.

  • Patent number: 11619088
    Abstract: A linear actuator includes a jacket defining an axis and a rod having an end cylinder tightly slidable in 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 a second variable volume compartments fluidly independent from each other, one of them being fluidly insulated and under vacuum, the other one being fluidly communicating with the outside environment. Upon the passage of the opposite end of the rod from the rest position to the working position, one of the variable volume compartments passes from a minimum volume to a maximum volume, in order to suck the rod and automatically recall the opposite end from the working position to the rest position.

The cylinder has a sliding surface against which the piston rests with a sealing element. A braking force that acts upon the piston can be applied using the air pressure generated in the receiving space because the piston is displaced, the receiving space being connected to the environment via an air-conducting connection to reduce the air pressure. In order to improve the braking effect of the sliding element, the sealing element of the piston and the sliding surface of the cylinder can contact each other in at least some areas via a defined rubbing surface geometry, the peak-to-valley height of the sliding surface being <1 ?m and the peak-to-valley height of the facing surface of the sealing element being=4.5 ?m in at least some areas.

  • Patent number: 7455154
    Abstract: A shock absorber with a shock absorber body having a cylinder. A piston is moveably guided in a receiving space of the cylinder. When the piston is moved, an air pressure generated in the receiving space exerts a braking force that acts on the piston. For air pressure reduction, the receiving space has at least one opening that produces an air-carrying connection between the receiving space and the environment. The shock absorber body has a simple design if the piston or the cylinder contains a receptacle into which an insert piece is inserted in a frictionally engaging fashion and if the opening is positioned between the insert piece and the wall of the receptacle that is touched by the insert piece.

    Abstract: A ranch gate arm assembly which incorporates a gate arm that is mounted to allow swivelling about a longitudinal pivot when an external man or machine force is applied to either side of the gate arm thereby inducing the gate arm to swing out, and two torsion springs, one assembled on each side of the ranch gate arm which push against correlating sides of the gate and push the gate back to a center position after the external force has passed completely through the opening. This gate arm assembly is equipped with a smoothing release assembly, which eliminates the jolt force caused by the quick returning of the gate assembly to the center position that the gate was originally in before the external force was applied.

    Abstract: A string type air damper includes a cylinder formed in a tubular shape, defining a guide hole at one end portion thereof, a piston, which moves in the cylinder, a helical spring for biasing the piston toward the other end portion of the cylinder, and a string member guided from inside of the cylinder to outside thereof through the guide hole. The piston and the string member are integrally formed. Since the string member is formed integrally with the piston, unlike a method according to a related art, it becomes unnecessary to form a loop at the base end portion of the string member with a complicated work and form a hook portion at the piston and hook the base end portion of the string member at the hook portion of the piston. Therefore, the string type air damper can be very easily assembled.
