    Abstract: The invention relates to a regulating valve, which is attachable, in particular in a bore of a hydraulic door closer, executed with a female thread. The regulating valve has a body, adjoined by a regulating area, and a thread provided with an anti-rotation means. The thread with the anti-rotation element can be screwed into the female thread of the bore of the hydraulic door closer. In order to provide a regulating valve with a simple design while excluding unwanted adjustment of the regulating valve during the operation, the anti-rotation means includes a raised area, which can cooperate with the bore or the female thread of the door closer.

    Abstract: A door closer device comprises a body defining an internal chamber in which a piston is slidably received, the chamber, in use, containing hydraulic fluid. A valve is arranged in a passage in the body to permit the fluid to flow through the passage in both directions between spaces in the chamber at respective opposite sides of the piston. The valve has a first part axially adjustable along the passage and a valve member attached to said first part but movable axially relative thereto in the passage between extreme positions where it engages respective stop means on the first member, the valve member allowing fluid to flow unrestricted through an orifice at one end of the passage in one direction when in one of its said extreme positions, and at the other extreme position restricting flow through said orifice in the opposite direction. Preferably the valve member is made of a material having a greater co-efficient of expansion than the material of the body containing said passage, so that expansion or contraction of the valve member with temperature changes enables a more constant door closing speed to be obtained by increasing or decreasing the size of the orifice as the viscosity of the hydraulic fluid also changes with temperature changes.

    Abstract: A door closer for regulating the movement of a door panel with respect to its frame has a body enclosing a chamber and an adjacent cylinder having a head. A piston is reciprocable in the cylinder toward and away from the head and in accordance with the door panel motion. A spring in the chamber urges the piston toward the head. A duct through the piston controlled by a check valve permits liquid flow from the chamber to the cylinder, but not vice versa. A passage in the body extends between the cylinder, near the head, and the chamber. In that passage near the head is a throttle valve for restricting liquid flow, and in the passage near the chamber is a bypass valve for restricting liquid flow and for permitting increased flow under increased liquid pressure. There is also a bore in the body extending between the passage intermediate the throttle valve and the bypass valve and an adjacent part of the cylinder traversed by the piston.

    Abstract: A ball check valve is described having a fluid port, a ball moveable toward and away from the port, a seating surface surrounding the port and an elastomeric sealing element. The seating surface has a conical annular surface extending radially outwardly away from the ball and an annular ridge between the port and the conical surface. The sealing element has an outer sealing surface for contacting the conical seating surface and an annular groove for receiving the seating surface ridge. On its ball side, it has an annular outer surface and an inner sealing surface for contacting the ball. A sealing element retainer contacts the outer portion of the elastomeric sealing element outer surface on its ball side to hold it in position.
