Embodiment Construction

[0062] figure 1 and figure 2 The solenoid valve of the present invention is shown.

[0063] The magnetic part of this solenoid valve, which allows the magnetic flux circuit to be generated by the coil 17, consists of the valve body 4, the fixed core 3 and the flat movable core 10 made of ferromagnetic material.

[0064] The flat movable core 10 moves between the fixed core 3 and the lower part of the valve body 4 along the main axis of the solenoid valve.

[0065] The flat movable core 10 moving along the main shaft of the solenoid valve is subjected to elastic restoring force from the leaf spring 9 . This force, which can be adjusted during installation, is called preload.

[0066] The fluid part of the solenoid valve consisting of the valve body 4 , the fixed core 3 and the flat movable core 10 comprises a double-sided spool 12 . The fluid part of the solenoid valve allows to control the flow of air from the air supply hole 18 to the use hole or holes 19 or from the use...

Abstract

The solenoid valve includes an electromagnet (17, 4, 3, 10) consisting of a flat movable core (10), a fixed core (3) and a coil (17), the solenoid valve includes a valve body (4), the valve The body also belongs to the electromagnet and includes an opening (23) at the rear of the valve body (4), opposite the air supply hole (18), enabling the flat movable core (10), the fixed core ( 3) and the coil (17) are inserted, the valve body (4) is connected with the retaining ring (8) made of non-magnetic material, the leaf spring (9) is compressed in the retaining ring (8) and is flat and movable between the cores (10).

Description

technical field [0001] The invention relates to small solenoid valves often used to control compressed air distribution systems with core slides or spools. These small solenoid valves act as power multipliers and controllers. In fact, for small electrical power inputs, often less than 1W, the control pneumatic power of the outlet is greater than 1kW. Background technique [0002] The structural principle of the small solenoid valve is based on the electromagnet, and its movable element can have two structural types. [0003] The first type of construction is characterized by a cylindrical core that penetrates deeply into the central part of the coil belonging to the electromagnet. This structure is generally referred to as a plunger core solenoid valve. [0004] The second construction type is characterized by a flat shaped core which does not enter the central part of the coil. This configuration is generally referred to as a flat movable core solenoid valve. [0005] ...
