    Abstract: A door closer (20) is attachable to a door (24) and is formed with a chamber (44) in which a piston element (50) is movable to move fluid from the chamber to a reservoir (82) upon opening of the door. After the door (24) has been opened to a position, for example, of sixty to seventy-five degrees, continued opening of the door causes the fluid to be compressed within the chamber (44) and to be directed only through a back check valve (95) to the reservoir (82). This results in the development of an adjustable "back check" condition to provide a counterforce to the continued opening of the door. The adjustable valve (95) includes a spring biased ball (144), the biasing of which must be overcome by the force of the fluid being compressed in the chamber (44) to allow for fluid to pass through the valve to the reservoir (82).The chamber (44) is formed partially by a spring tube (38) having slots (192) formed in the interior wall thereof which extend radially beyond convolutions of spring (52) contained within the tube. The slots (192) allow the fluid, and gas bubbles entrapped therein, to be moved beyond the convolutions of the spring (52) and to be moved unimpeded into the reservoir (82). Otherwise, the gas bubbles would be trapped in the chamber (44) and would deleteriously affect the operation of the door closer (20).

    Abstract: A door closing apparatus includes a housing member defining a cylinder for receiving a reciprocable piston member. The housing also defines an opening for receiving a rotatable pinion meshing with teeth on the piston. The apparatus also includes a linkage assembly for operatively connecting the door closing apparatus between a door and a door frame. This linkage includes a drive member for rotating the pinion bidirectionally in response to respective opening and closing of the door. An adjustable biasing assembly is provided for urging the piston in a predetermined direction within the housing cylinder, and the housing is sealed to receive a predetermined amount of oil or other fluid for hydraulically regulating the piston motion. To achieve this regulation, the housing includes an arrangement of interconnected fluid carrying channels and one or more valve members are mounted in cooperation with the channels. Advantageously the valve members cooperate with the channels to provide an adjustable variable control over the reciprocal movement of the piston, as, for example, to adjust the close rate and latch rate of the associated door. In a preferred embodiment, a hold open assembly is provided and comprises a holding member joined for rotation with the pinion and a stop member for releasably engaging the holding member to hold the door open.
