Embodiment Construction

[0028] figure 1 , 2It is the electromagnetic valve 1 which concerns on one Embodiment of this invention. This solenoid valve 1 includes: a main body 10, a coil member 20, a fixed iron core 30, a movable iron core 40, a valve body 50, a cylindrical member 60, a biasing member 70, a buffer member 80, and a first spacer. member 90, and a second spacer member 95. In the solenoid valve 1, the main body portion 10 and the valve body portion 50 are made of a material having high corrosion resistance and chemical resistance. For example, it is a fluororesin such as PTFE or PFA. The fluororesin can be easily processed into a desired shape by cutting or the like.

[0029] Main body 10 such as figure 1 , 2 As shown, the first flow path portion 11 and the second flow path portion 12 for inflow and outflow of fluid are provided, and each member is accommodated and protected. The main body 10 has a valve chamber (valve chamber) 15 inside. In the valve chamber 15 , the first flow pat...

Abstract

The invention relates to a solenoid valve. The invention provides the solenoid valve having high driving durability in which the generation of noise can be effectively suppressed with a simple configuration. Provided is the solenoid valve including a cylindrical member 60 made of a nonmagnetic material interposed between a coil member 20 and a fixed iron core 30 and a movable iron core 40, a biasing member 70 which continuously biases the movable iron core in the direction of a valve seat, a cushion member 80 made of an elastic body arranged at the portion of the fixed iron core that contactswith the movable iron core, a first spacer member 90 made of a molded resin body which is attached to a fixed iron core side end of the movable iron core, is in continuous contact with the inner peripheral surface of the cylindrical member, and abuts against the cushion member when the movable iron core moves in the direction of the fixed iron core, and a second spacer member 95 which is mounted on an outer periphery of the movable iron core on the valve body side and is in continuous contact with an inner peripheral surface of the cylindrical member together with the first spacer member so asto form a space S between a side surface of the movable iron core and an inner peripheral surface of the cylindrical member.

Description

technical field [0001] The present invention relates to a solenoid valve in which a movable iron core excited by a coil member advances and retreats relative to a fixed iron core, and particularly relates to a solenoid valve in which generation of noise is suppressed. Background technique [0002] The solenoid valve includes a coil member, a fixed iron core and a movable iron core that are excited by energization to the coil member, and a valve body provided on the movable iron core. The solenoid valve operates to excite the fixed iron core and the movable iron core, whereby the movable iron core advances and retreats relative to the fixed iron core. In the solenoid valve, the opening and closing of the flow path by the valve body is performed by utilizing the forward and backward movement of the movable iron core. The solenoid valve has an advantage that the response speed is quicker compared with the operation performed by a motor or the like. [0003] In the solenoid va...
