    摘要： 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.

    摘要： A method for making a hydraulic door closer includes the steps of molding material to form an elongated single-piece housing having a longitudinal cylindrical bore extending from a first open end thereof to a closed second end, a transverse intersecting bore, and mounting feet; installing a spring within the cylindrical bore at the closed end of the housing; installing a piston within the cylindrical bore in contact with the spring, the piston having a toothed rack thereon and an opening in each end to permit passage of fluid therethrough; installing a pinion gear in the transverse intersecting bore in meshed engagement with the toothed rack; installing an endplug with a port in the first end of the longitudinal cylindrical bore; and inserting a valve device through the port, for controlling flow of fluid through the piston, and for thereby controlling closing speed of the door. The single-piece housing as well as other components may be molded from metal or polymeric materials. Polymeric materials are preferred for their flexibility, lubricity, and moldability.

    摘要： A door closer wherein a housing defines a fluid-containing space for a reciprocable damping piston which divides the space into a first and a second compartment. The piston carries a check valve which is closed during movement of the piston in a first direction while the door panel is being opened and which is open when the piston moves in the opposite direction. A channel is provided in the housing to permit fluid to flow from the first compartment into the second compartment during a first stage of movement of the piston in the first direction. The check valve has a body which defines a passage for the flow of fluid between the compartments and is surrounded by a seat having one or more grooves which are only partially overlapped by a spherical or non-spherical valving element during movement of the piston in the first direction to thus establish a relatively small path for the flow of fluid between the compartments, at least during a second stage of movement of the piston in the first direction, such second stage following the first stage. Springs in that compartment from which fluid is expelled during movement of the piston in the first direction oppose such movement of the piston, and an additional spring can be provided to bias the valving element against its seat.

    摘要： 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.

    摘要： 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.

    摘要： A check assembly using compressible fluid for linearly dampening the closing movement of a door includes a cylindrical, hollow housing having a cavity defined therein with first and second ends. Slidably mounted within the cavity and attached to the door is a piston of substantially the same cross-sectional area as the cavity. The piston has flap-type, relief check valves allowing free passage of compressible fluid through the piston only during motion of the piston in the door opening mode. The check assembly further includes longitudinal grooves fabricated circumferentially around the cavity and of a dimension such that the seal of the piston against the cavity wall is broken at different points during movement of the piston allowing compressible fluid to flow from one side of the piston to the other. Finally, the check assembly includes a fluid bypass continuously communicating compressible fluid from one end of the cavity to the other thereby defining a closed loop system. The bypass includes a variable orifice comprising an orifice and a needle valve such that the rate of fluid flow through the bypass may be adjusted to allow the same assembly to be used with doors of different weights and to compensate for linkage wear.
