Abstract

PURPOSE: To reduce the size of the entire valve body of and increase the life of a hydraulic control valve by sliding the valve body in rectilinear flow passage and reducing the moving distance of the valve body.
CONSTITUTION: A hydraulic control valve 10 is split into front and rear pieces 11 and 12, which are coupled by a piston 14. An intermediate passage 20 is formed on the same axis as the inlet 19 of the piece 11 to communicate with a valve sliding chamber 21 to thus connect the chamber 22, intermediate passage 23 and outlet 24 of the piece 12 to form a rectilinear flow passage between the pieces 11 and 12. A spring 17 is interposed between the head 25 of the piston valve body 15 sliding in the flow passage and the partition wall 18 to be sealed with a flexible cover 16. A throttle valve 28 is provided at the inlet of the heat 25 of the valve body 15 to reduce the passage 20 upon movement of the valve body 15 to thereby control the returning refrigerant of an air conditioner. The entire valve body is decreased in size and the valve body 15 is provided along the fluid flow to thereby prevent the damage of the valve body and increase the life of the valve body.
