    摘要: Hydraulic door closer apparatus comprises a cylinder, a piston disposed in the cylinder, linkage means coupled to the piston for transmitting forces between the piston and a door, and a hydraulic circuit for controlling movement of the piston in the cylinder. A temprature responsive control element is provided in the hydraulic circuit to alter the characteristics of the circuit in response to changes in ambient temperature or temperature of the fluid within the closer.
