    Abstract: A door closer or operator includes a pivoting pinion on the door closer housing for transmitting door motion, and a cam connected thereto. A connecting member extends along a spring and engages the peripheral edge of the cam. Rotation of the cam causes a change in length of the portion of the connecting member between the position tangent to the cam peripheral edge and the spring second end to expand or compress the spring, resulting in a force transmitted along a longitudinal axis of the connecting member as a result of spring deflection. The cam peripheral edge has a profile with a varying radial distance between the cam axis and the connecting member at the position tangent to the cam peripheral edge such that the radial distance is changed as the spring expands or compresses to maintain a desired constant torque about the axis of the cam and pinion.

    Abstract: A retractor element includes a rigid slide connected between a latch bolt and a solenoid plunger for movement between a first position and a second position, the slide operably connected to plunger. A pivoting link defines a slot having an inner end portion extending transversely, the slot configured for pivoting the link when the slide moves between the first position and the second position of the slide. When the retracting mechanism is energized the plunger retracts causing movement of the slide to the second position of slide and the pin to enter the transverse end of the slot in the link. A bearing surface intersects the path of movement of the pin such that significantly less current is required for retaining the plunger in the retracted position than to retract the plunger for blocking the return of the latch bolt to the projected position.

    Abstract: A door closer comprises a piston cooperating with a rotating pinion. Upon rotation of the pinion in the door opening direction, the piston moves toward the second end of the housing forcing fluid from a second variable volume chamber through a passage to a first variable volume chamber and compressing a spring assembly for storing energy. The spring assembly urges the piston toward the first end of the housing for forcing fluid from the first variable volume chamber to the second variable volume chamber and rotating the pinion in the door closing direction. A controller controls the position of a valve in the passage based on the sensed angular position of a door and the position of the valve for determining the amount of hydraulic fluid flowing through the valve.
