摘要： A low-bulkiness hinge for closing a closing element anchored to a stationary support structure, such as a wall, a frame or a floor includes a hinge body which includes a longitudinal operating chamber defining a first axis, a pivot coupled to the hinge body to rotate around a second axis between the opening and closing positions of the closing element, and a slider slidable in the operating chamber along the first axis. The operating chamber has a first seat for the pivot and a second seat for the sliding of the slider, which includes a shaft and an operative head that are mutually coupled. The hinge body has a first opening for inserting, perpendicularly to the first axis, the operative head into the second seat and a second through opening for inserting, coaxially to the first axis, the shaft into the housing. The hinge further has the shaft and the operative head fixed to one another after insertion in the second seat (so as to form a unitary assembly integrally slidable along the first axis.

摘要： A hinge for the rotatable movement of a closing element, such as a door, a window, a shutter or the like, includes a fixed element anchorable to a stationary support structure and a mobile element anchorable to the closing element. The fixed and movable elements are mutually coupled so as to rotate with respect to each other between an open position and a closed position. One of the fixed or movable element includes a working chamber, with a plunger disposed to slide along a longitudinal axis and operatively coupled with the other one of the fixed or movable elements so that the sliding of the plunger corresponds to a rotation of the movable element.

摘要： A laundry treating appliance for treating laundry items according to an automatic cycle of operation can include a cabinet defining an interior and having a top panel that at least partially defines an access opening to the interior. A lid is rotatable between a closed position and an opened position to selectively open or close the access opening. At least one hinge assembly couples the top panel with the lid. The at least one hinge assembly can include a hinge housing coupled to the top panel. A cam is received within the hinge housing and coupled to the lid. A snubber housing is coupled to the hinge housing and has a damper receiving portion. A damper is at least partially received within the damper receiving portion.

摘要： A cam action door closer comprising a body, a spring, a speed control channel system and a latching control channel system, a closing control piston having a piston head and a circular side. The closing control piston has a cutting on the side of the closing control piston and on the piston head, the cutting forming a control edge at its end. The cutting has a length between the piston head and the control edge. The speed control channel system comprises a speed connecting channel, which is located in such a way that the control edge is arranged to close it.

摘要： This disclosure is generally directed to a hydraulic door closer, and more specifically is directed to a hydraulic storm or screen door closer that has a fluid overflow chamber providing fluid volume and pressure control for both expanded and contracted fluid at different temperatures. The disclosed hydraulic door closer comprises a fluid overflow chamber adapted to hold sufficient fluid to maintain required operating fluid or oil levels at different temperatures, and to ensure proper closer performance under both extreme high and low temperature conditions.

摘要： 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.
