徴とするエアクラツチの空気圧制御弁。 an air valve body that supplies air pressure from an air pressure source to the air clutch while adjusting the pressure in response to the amount of depression of the clutch pedal; a first valve body that supplies air pressure from the air pressure source to the air clutch when the clutch is connected; In the air pressure control valve of the air clutch provided in the air valve body, a second valve element is connected to the pedal and releases the air pressure supplied to the air clutch when the clutch is disengaged. 1
A spring member is provided, and the maximum air pressure is set by the action of the spring force of the first spring member and the air force acting on the diaphragm connected to the second valve body.
Providing a slidable rod in relation to the valve body,
A piston that receives hydraulic pressure from a clutch master cylinder that converts the amount of depression of the clutch pedal into hydraulic pressure is connected to this rod, and second and third spring members are placed concentrically between this rod and the second valve body. A spring force transmission mechanism is provided that operates in series while being arranged in a shape, and transmits the spring force of the second and third spring members to the second valve body, and the spring force transmission mechanism in the cylindrical body is provided to the second valve body. A rod is formed that extends toward the mechanism, and this rod is connected to a spring force transmitting member of the spring force transmitting mechanism, so that the mass of the spring force transmitting member prevents vibration of the second valve body and the diaphragm. Air pressure control valve for air clutch.
