PROBLEM TO BE SOLVED: To reduce magnetic resistance by shortening travel distance of a plunger and reduce electric power for driving a four way solenoid valve and holding its condition. SOLUTION: This four way solenoid valve is provided with a valve main body 1 provided with one end connection 1a on a side face on one side, three end connections 1b, 1c, 1d on a side face on the other side, and a circulation chamber R formed in the whole region of a group of end connections among one end connection 1a and three end connections 1b, 1c, 1d in the inside, the plunger 20 moving in the axial direction inside the valve main body 1, and a sliding valve element 3 connected with the plunger 20, brought into pressure-contact with three end connections 1b, 1c, 1d, and arranged to slide. The sliding valve element 3 communicates two end connections among three end connections 1b, 1c, 1d through a recessed part 3a for communication and communicates the other end connections through the circulation chamber R. Three end connections 1b, 1c, 1d are arranged in a triangular shape for its valve seat face. COPYRIGHT: (C)2006,JPO&NCIPI
