Problems solved by technology

Solenoids that must be powered continuously to hold the valve member in the actuated position are not ideal in applications where the power consumption of the solenoid is a concern, such as where there is a limited source of electrical power (e.g., battery-powered valves) of
Additionally, significant heat buildup can occur in the solenoid which must be continuously powered to hold the valve member in the actuated position

Abstract

The invention discloses a control valve, which has a valve body, a seat member, a valve member and a solenoid comprising a shell, a barrel and a coil. The valve member has a head set in the cylinder body and a valve part set in the valve body. The valve part has a seat engagement member. The seat engagement member operates to open and close the ports in the valve body when the valve member slidesbetween the first and second positions. The permanent magnet arranged in the barrel exerts a variable value of attraction on the valve member in the opposite direction to the bias force generated by the bias component. The current pulse applied to the coil changes the variable value. When the attraction is greater than the bias force, the permanent magnet pulls the valve component to the second position, and when the attraction is less than the bias force, the valve component returns to the first position.

Description

[0001] Cross-reference to related applications [0002] This application claims the benefit of US Provisional Application No. 62 / 576,257, filed October 24, 2017. The entire disclosures of the above applications are incorporated herein by reference. technical field [0003] The present disclosure relates to control valve assemblies. More specifically, the present disclosure relates to self-locking solenoid-actuated valve assemblies that can be used in a variety of applications, including but not limited to pneumatics. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] Solenoids are well known electromechanical devices used to convert electrical energy into mechanical energy, particularly into short-stroke mechanical motion. Therefore, solenoids have long been used to drive valves in response to electrical signals. For example, it is known in the art to use a solenoid to ...
