Claims

[Scope of utility model registration request]

An upper chamber 22 is formed above the upper valve seat 19 by a tube 20 and a suction element 21.
A plunger 24 is inserted inside with a spring 23 interposed on the side of the attractor 21, a solenoid valve coil 25 is attached to the outside of the tube 20, and a valve port B26 is provided in the center of the lower part of the upper valve seat 19. Provided with the valve port B26 and the outlet vibe B2
7 through a communication hole 28, and a lower valve seat 31 having a valve port C30 in the center that communicates with an outlet vibe C29 is provided below the upper valve seat to form a valve case 32, and an inlet port to this valve case. A vibrator 33 is provided on the upper valve seat 19, and an upper chamber 22 and a valve case 3 are installed at a position away from the valve seat.
A through hole 42, 42 is provided to communicate with the plunger 24, and an interlocking pin 4 extending from the lower surface of the plunger 24 is provided in this through hole.
3 is inserted so as to be able to move up and down, and on the other hand, inside the valve case 32, it has a flat end part 34 in the center and a gap 44 of a leaf spring is inserted outwardly from the flat end part 34.
The ball 37.
38 is held in a holder 39 with some play in the balls, and the leaf springs of the leaf springs 35 are held so that each of the balls 37 and 38 selectively closes the upper and lower valve ports B26 and C30. A three-way solenoid valve characterized in that an outer circumferential portion 41 is sandwiched between outer circumferential portions of an upper valve seat 19 and a lower valve seat 31, and the lower end of the interlocking pin 43 is in contact with the upper surface of a leaf spring.
