Abstract

The electromagnetic coil assembly in the electromagnetic valve includes: a coil portion (20) disposed in a coil frame (21) on an outer peripheral portion of a cylindrical portion (26) of the valve body portion (10); a closed cylindrical portion (26) The suction piece (24) at one end; and the shell (16) that covers and accommodates the coil part (20) and the resin coil frame (21) inside, and the O-ring (30) seals the circle of the valve main body part (10) The gap between the outer peripheral portion of the cylindrical portion (26) and the inner peripheral portion of the cylindrical portion (22A) of the lower plate (22).

Description

technical field [0001] The present invention relates to a solenoid valve incorporated in an air conditioner, an automatic vending machine, a refrigerator, etc., and controlling the flow of a fluid such as a refrigerant. Background technique [0002] In the solenoid valve, for example, as shown in Patent Document 1, the solenoid coil assembly can be assembled to the valve main body part already connected to the piping pipe by field work (in Patent Document 1, in Figure 7 Solenoid valves, also known as plunger housings, are used in practical applications. In such solenoid valves, for example, as in the accompanying drawings of this application Figure 12 As shown, the electromagnetic coil assembly 6 is detachably assembled to the valve main body 1 connected to the piping pipe 2 and the piping pipe 4 . The electromagnetic valve includes a valve main body 1 and an electromagnetic coil assembly 6 as main elements. [0003] The cylindrical part of the valve main body part 1 has...
