A double-solenoid type electromagnetic valve having two solenoids integrally connected is disclosed. The solenoids of the electromagnetic valve have the same structure and the same external shape and have connecting mechanisms with engaging rims and engaging grooves on the sides. By connecting the connecting mechanisms with each other, the solenoids are closely connected and overlapped without any gap between them.
摘要:
An electromagnetic pilot type selector valve which can serve as a double-solenoid type selector valve or a single-solenoid type selector valve by merely increasing or decreasing the number of solenoid mechanisms and by providing a few component parts. This selector valve includes large and small pistons having different pressure receiving areas for driving a main valve disc. When two solenoid mechanisms are mounted, the main valve disc is switched over by pilot fluid pressure alternately applied on the two pistons. When one solenoid mechanism is mounted, the main valve disc is switched over by switching pilot fluid pressure applied on the large size piston, while the main valve disc is constantly pushed in one direction by pilot fluid pressure applied on the small size piston.

A tube coupling for fluidic apparatus connects flexible hose or other tubes to ports of different sizes and shapes provided in fluidic apparatus. The tube coupling comprises a base to be attached to a port in a fluidic apparatus, a tube connector to connect a tube, and a metal holder that keeps in position the tube connector attached to the base.

In a pilot-driven spool type change-over valve, a lateral width of a valve body and sizes of each port and valve hole are efficiently determined in such a manner that flow rate or fluid per unit time reaches the highest value without substantially impairing responsiveness in order to increase ability to change over the fluid. An inner diameter of the valve hole a lateral length of an opening of the port are set to substantially the highest value as determined by lateral width of the valve body, and longitudinal diameter a of an opening of each port, i.e. length in axial direction in the valve hole, is set to such a size that a characteristic value given by a/W.sup.2 is 1.5 to 2.2.times.10.sup.-2.

A pipe joint is provided wherein quick joints assembly are installable in two ports and in a fluid pressure apparatus such as a solenoid transfer valve as in the prior art, while joints with a female thread are interchangeable with the guide joints so as not to rotate even when male screw members for piping are screwed in. The quick joints and the joints with a female thread are interchangeably installed in a fluid pressure apparatus in which two ports are switched and supplied with a pressurized fluid. Although the quick joints and the joints with a female thread can be installed as in the prior art, the joints with a female thread are integrally connected and fixed between the quick joints and the joints with a female thread via a connection member so as not to rotate even when male screw members for piping are screwed in.

A fixture fastens pipe joints 5 to multiple ports 35A, 35B, 36A and 36B that are arranged substantially in a line in a port block 4 attached to the valve body 6 of a change-over valve 1. The fixture comprises a metal fixture insertion groove 40 cut from one side of the port block 4 to a depth reaching the individual ports, a metal fixture 41 having multiple recesses 44 arranged along one edge thereof so as to come into engagement with the pipe joints 5 when inserted in the metal fixture insertion groove, and bolt s 48 for fastening the metal fixture 41 and port block 4 to the valve body 6.

The present invention aims to provide a simply constructed pilot operated directional control valve having a position detecting function, capable of detecting, utilizing a light sensor, operating positions of a valve member such as a spool. To achieve this, an object to be detected 21 is formed on the end face adjacent to a breathing chamber 9, of a piston 2a; there is formed a recess 22 in which the object to be detected 21 is fit and which is disposed in the wall surface of the breathing chamber 9, in a casing 4; and an optical sensor 25 is mounted on a position facing the recess 22 in the casing 4 for projecting and receiving light relative to the object to be detected 21 through a through hole 23, whereby operating positions of the piston 12a, or the spool 6 are detected based on the light reflected from the object to be detected 21.
