OPENED TYPE THREE-WAY VALVE

摘要

PURPOSE: An opened type three-way valve is provided to keep the three-way valve opened all the time with having a single intake port and two discharge ports. CONSTITUTION: An opened three-way valve includes: a tube(120); an intake pipe(141) communicated with a side of the tube to flow refrigerant to the tube; a first and a second core(131,135) connected to both ends of the tube, forming a first and a second path(132,136) lengthwise the tube to communicate the inside of the tube with outside; a plunger(150) mounted between the first and the second core, having a distance with the inside of the tube to form a fluid path toward the intake pipe; a first and a second spring(171,175) installed between the cores and both ends of the plunger respectively to keep the both ends of the plunger separated from each core; and a firs and a second coil(181,185) covering both ends of the tube and closing the first and the second path selectively by moving the plunger in the opposite direction of elasticity applied to the plunger. A single three-way valve having two discharge ports is adopted instead of plural valves. Therefore, refrigerant gas is supplied to two parts and the manufacturing costs are reduced.
