GOVERNOR DEVICE

摘要

To keep the opening amount of a port constant even if a temperature change occurs. This governor device (1) is characterized in that the device comprises a cylindrical part (49) of which axial both ends are opened, a valve seat formed at the opening edge of a control port (52) opened at one end of the cylindrical part (49), a valve element (18) capable of closing the valve seat and controlling its open amount relative to the control port (52) according to its raised height from the control port (52), and a temperature correction member (54) connected to the valve element (18) through a balancer spring (53) and correcting the thermal change in the open amount resulting from the thermal expansion or the thermal contraction of the cylindrical part (49) in the axial direction.
