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.

A hinge for the rotatable movement of a door or a similar closing element anchored to a wall or a similar stationary support includes a fixed element adapted to be coupled to the wall or a similar stationary support and a movable element adapted to be coupled to the door or a similar closing element. The fixed and movable elements are coupled to mutually rotate around a first longitudinal axis between an open position and a closed position.

An example door closer includes a casing and a pinion rotatably mounted to the casing. The pinion is operable to rotate through a plurality of movement zones, and the door closer is configured to exert forces on the pinion as the pinion moves through the plurality of movement zones. The door closer further includes a plurality of adjustment mechanisms, each operable to adjust the force exerted on the pinion as the pinion travels through a corresponding movement zone. The casing is provided with indicia that correlate each of the adjustment mechanisms to the corresponding movement zone.

An exemplary door closer includes a body, a regulation screw, and an indicator. The body includes a surface and a cavity extending from the surface into the body, and the cavity includes an internal threading. The regulation screw is mounted in the cavity and includes an external threading engaged with the internal threading. The indicator is engaged with the regulation screw and positioned at least partially within the cavity. The indicator is positioned to project beyond the surface when the regulation screw is withdrawn to a reference position relative to the body.

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.

A liquid sealed damper includes: an attachment portion attached to a peripheral portion of an opening of a vehicle or an opening and closing member for covering the opening; a contact portion to which an external force is input; an insulator configured to isolate vibration and connect the attachment portion and the contact portion; a main liquid chamber in which working liquid is sealed, the insulator serving as a wall portion of the main liquid chamber; an auxiliary liquid chamber divided from the main liquid chamber by a partition member and having a wall portion formed of a diaphragm; and an orifice passage formed in the partition member and communicating with the main liquid chamber and the auxiliary liquid chamber. The partition member has an inner gap in the shape of a recess, and a part of the diaphragm is inserted into the inner gap.

A decelerated hinge for furniture, which comprises a hinge arm, a hinge box fixable to a door and swingably connected to the hinge arm by an articulation axis at a rear wall of the hinge box, elastic closing means for closing the hinge and a linear-type decelerating device comprising a housing body, a slider, a fluid damper and elastic return means, wherein the hinge box has at least one opening in at least one of a front and/or side walls, and wherein the housing body has at least a retaining protrusion conformed and arranged to be inserted in the at least one opening in such a way to be protruding outside the hinge box, wherein the retaining protrusion inserted in the opening cooperates with fixing means by which the housing body is fixed in the hinge box.

Systems and devices to control rotational and/or arcuate motion are provided herein. In some examples, a hinge system is configured to replace a conventional door hinge and to control motion of the door. In some examples, a hinge system is configured to replace a conventional door hinge and to control motion of the door by employing a shear thickening fluid. In some examples, a door closure system is configured to replace a conventional door hinge and to control motion of the door by employing two opposing springs.
