Problems solved by technology

[0008] However, the anti-surge valve may not function smoothly when the diaphragm (which is formed of rubber or plastic resin less durable than the materials forming the other constituent elements of the anti-surge valve) is corroded or torn
Therefore, detrimental to the function of the engine

Abstract

The invention provides an anti-surge valve. The anti-surge valve opens or closes a path depending on a negative pressure formed at an intake manifold, and includes an operating unit movable in a direction in response to the negative pressure, a spring means provided to push the operating unit in a direction opposite to the moving direction of the operating unit in response to the negative pressure, a spring mounting portion for mounting the spring means, and a diaphragm disposed to cover an outer surface of the operating unit. The diaphragm may be formed in a substantially hollow cylindrical shape and include a circumference portion formed along a circumference of an opened top surface of the diaphragm, a coupling portion formed along a circumferential direction from an outer end of the circumference portion, and a side portion extended substantially vertically from an inner end of the circumference portion, and has substantially uniform outer and inner diameters.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0147777 filed on December 17, 2012, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to an anti-surge valve, and more particularly, to an anti-surge valve with improved durability. Background technique [0004] Generally, the flow of intake air in a CGN (Compressed Natural Gas, compressed natural gas) engine is controlled by an electronic throttle valve. During a tip-out condition in such CNG engines, the throttle valve is closed. When the throttle valve is closed, intake air recirculation may occur. [0005] In particular, when a turbocharger is installed, noise and vibration may occur when the blades of the compressor come into contact with the return flow of the intake air. In addition, the durability of the turbocharger may be impaired. [0006] In...
