暖機装置。 In a vehicle warm-up device in which an exhaust brake valve rotatably disposed in an engine exhaust pipe is used as a warm-up valve, a valve body having an internal exhaust passage formed in the middle of the exhaust pipe is provided. Insertion holes are formed in the valve body located upstream and downstream of the exhaust brake valve that opens and closes the exhaust passage, and pistons that open and close these insertion holes and the piston are always energized in one direction. A pressure regulator equipped with an energizing member is provided, and when the exhaust brake valve is closed,
The vehicle is characterized in that the piston is actuated by exhaust pressure on the upstream side of the exhaust brake valve to open the insertion hole and form a passage connecting the upstream side and the downstream side of the exhaust brake valve. Warming device.
