Patent number: 12071805Abstract: A hydraulic door closer capable of reducing oil-pressure therein at high temperature, comprises a housing with an oil chamber, an oil storage cavity, and a piston in the housing of the hydraulic door closer. The oil storage cavity is in communication with the oil chamber; when the oil temperature increases, hydraulic oil in the oil chamber and oil storage cavity generates an increased oil pressure move the piston, whereby volume of the oil storage cavity is enlarged, such that oil from the chamber will flow into the cavity, to reduce the oil pressure of the chamber and cavity. When the oil temperature decreases, the oil pressure in the chamber and cavity is reduced, whereby the storage piston restores its original position, whereby volume of the cavity will be reduced, and the oil in the cavity flows back into the chamber. The pressure in the oil chamber is reduced when the hydraulic oil expands due to increased temperature to prevent failure of the seal and to avoid hydraulic oil leakage.Type: GrantFiled: August 13, 2021Date of Patent: August 27, 2024Assignee: CMECH (GUANGZHOU) LTD.Inventor: Wei Jin Chao

Publication number: 20090139049Abstract: A stop damper including a damper member with a cylinder. A piston is moveably guided inside a receiving space of the cylinder. 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.Type: ApplicationFiled: October 26, 2006Publication date: June 4, 2009Inventors: Ulrich Bantle, Jurgen Eschle

Publication number: 20090094789Abstract: Universal impact-hinder device, comprising a body (1); a guiding pin (4) arranged at the closed first end of an inside cylindrical cavity of the body (1), a spring (7) on the guiding pin (4); a ring (5) at the opposite end of the cavity; and a piston having T-shaped head and an inside cavity in which the spring (7) is supported, which piston can move until the ring (5), while the guiding pin (4) is within the inside cavity of the piston. The T-shaped head is provided with a groove and a movable O-ring (6) within that, having two end positions in the groove. In first end position a surface of the groove having artificial damages (31) and the contacting O-ring (6) determine a first flow-through capacity, in second end position an orifice (21) between the cavity of the body and the groove determines a greater second flow-through capacity.Type: ApplicationFiled: March 9, 2007Publication date: April 16, 2009Inventor: Jozsef Bereznai

Patent number: 7455154Abstract: 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.Type: GrantFiled: April 14, 2006Date of Patent: November 25, 2008Assignee: Karl Simon GmbH & Co.

Patent number: 7444714Abstract: 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.Type: GrantFiled: September 12, 2005Date of Patent: November 4, 2008Assignee: Prairie Valley Mfg Inc.Inventor: Donald Lenz
