Embodiment Construction

[0032] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0033] 1 to 4 show an embodiment of a solenoid case (hereinafter simply referred to as "housing") and a solenoid valve in the present invention. In the solenoid valve of the present invention, the plunger, the plunger sleeve, etc., and the structure of the valve body are also the same as those of the conventional solenoid valve shown in FIG. In addition, in the following description, the upper side of the front view of FIG. Direction, the back side of the front view is taken as the rear direction.

[0034] The casing 1 is formed into a U-shape by a strip-shaped magnetic body, has a first curved portion 2 at the junction of the upper surface 1a and the back surface 1b, and has a second curved portion 3 at the junction of the back surface 1b and the lower surface 1c. A form in which the upper surface, the back surface, and the lower surface of the coil case 4 are cov...

Abstract

The invention not only prevents the mounting jut from deforming, suitably fixes the stopping part, but also realizes the miniaturization of a solenoid case and a solenoid valve. The solenoid case uses the tape part to form two flexural part (2, 3) with a U-shape, wherein a square curve part (2) with two curve parts (2, 3) is continuous and equipped with an installing surface (an upper surface) (1a) of the stopping part (7) for fixing the plunger sleeve (23), and the mounting jut (6) integrated with a case (1) near the edge beside the curve part (2) of the installing surface (1a), and the stopping part (7) is equipped on the installing surface (1a) through the mounting jut (6). Because the mounting jut (6) is far away from the curve part (2), the stress generated when the case (1) is processed can be used on the mounting jut (6), which prevents the mounting jut from deforming. Due to no mounting jut (6) arranged near the curve part (2), the size of the stopping part (7) is not needed to think about when deciding the size of the case (1), realizing the miniaturization of the case (1).

Description

technical field [0001] The present invention relates to a solenoid casing and a solenoid valve, in particular to a casing with a stopper for a plunger sleeve for fixing the solenoid valve and a solenoid valve with the casing. Background technique [0002] Conventionally, solenoid valves that open and close valves using magnetic force have been widely used in the flow control of refrigerants in air conditioners and the flow control of fuel gas, air, warm water, liquid fuel, etc. in bathrooms and shower rooms. As such a solenoid valve, there is, for example, a product described in Patent Document 1, which is composed of a drive unit 20 and a valve body 40 as shown in FIG. 6 . [0003] A coil 21 is housed in the drive unit 20 , and a plunger 22 that moves up and down and a cylindrical plunger sleeve 23 that extends along the axial direction of the plunger 22 are disposed on the shaft core of the coil 21 . , a spool 24 connected to the plunger 22, and a suction block 25 for att...
