Problems solved by technology

[0004] This solenoid valve device can quickly move the armature, but since the space in which the armature is housed is relatively close to the outside, there is a problem that as the armature is driven, the fluid enters and exits from the outside through the breathing hole. Contaminants intrude into the space accommodated in the armature

Embodiment 1

[0040] refer to Figure 1 to Figure 4 The solenoid valve device of Embodiment 1 will be described. Below, with figure 2 The left side of the paper is the bottom (bottom) of the solenoid valve body, and the right side of the paper is the head (upper).

[0041] The solenoid valve main body 3 is a spool type solenoid valve, for example, used in a hydraulically controlled device such as an automatic transmission of a vehicle. Such as figure 2 , Figure 4 As shown, the device obtained by assembling the solenoid valve main body 3 to the valve body 2 is called the solenoid valve device 1 .

[0042] The solenoid valve main body 3 is configured such that a valve unit 5 serving as a valve for adjusting the flow rate of a fluid is integrated with a solenoid unit (linear solenoid) 10 serving as an electromagnetic drive unit. Details of the attachment of the valve unit 5 will be described later.

[0043] The valve portion 5 is composed of a sleeve 6 provided with an input port 6a (...

Embodiment 2

[0073] Next, refer to Figure 5 The solenoid valve device of the second embodiment will be described. In Example 2, instead of the O-ring 40 in Example 1, a circumferentially continuous annular ring that protrudes from the valve side end surface of the solenoid case 11 and abuts on the outer surface of the valve body 2 is used. The convex portion 11k (annular seal member) is different. In addition, since it has the same structure as the said Example 1, description of the structure which overlaps is abbreviate|omitted.

[0074] As described above, since the sealing member is the convex portion 11k provided on the end surface of the solenoid case 11 on the valve portion side, the structure is simple. Furthermore, the sealing structure can be constituted only by attaching the solenoid valve main body 3 to the valve body 2 , and compared with the case where other components such as the O-ring 40 are used, the work of positioning and the like is reduced, and the assembly property...

Abstract

A solenoid valve main body (3) is provided with: a respiratory hole (6h) which passes radially through a sleeve (6) on the side of the sleeve (6) that faces a solenoid part (10), and which interconnects a space (A) formed between an armature (34) and a spool (7) with the outside at least when the armature (34) is in a prescribed area; a first opening (11d) facing a valve part (5) and opening to the outside; a second opening (11h) opening to the outside; and a respiratory channel inside a solenoid case (11) which is interconnected at one end with the first opening (11d) and interconnected at the other end with the second opening (11h). A passage between the respiratory hole (6h) and first opening (11d) of the solenoid valve main body (3) is ensured, and annular sealing means (40, 11k) are placed in the periphery of the sleeve (6) to secure the solenoid valve main body (3) and the valve body (10) in such a manner as to block the passage between the respiratory hole (6h) and the outside.

Description

technical field [0001] The present invention relates to solenoid valve arrangements, and more particularly to solenoid valve arrangements for hydraulic control of hydraulic circuits. Background technique [0002] As a conventional solenoid valve device for hydraulic control, a solenoid valve device having a valve part having a spool housed in a sleeve and a solenoid part having a solenoid part is known. A pipe case that accommodates a solenoid molded body obtained by covering an armature and a solenoid that drives a spool in the axial direction with a resin, and the solenoid valve device is configured Between the pressure source of the pump or accumulator and the load, the spool is driven to supply the control oil with the pressure and flow rate adjusted to the load. [0003] Since the driving stroke of the spool is relatively large, when the solenoid unit is driven, the fluid in the space in which the armature is accommodated acts as resistance, which may hinder the rapid ...
