Abstract

The present invention provide for an anti-surge valve for a vehicle includes: a diaphragm, a valve cup; a coupling member; and a spring. The diaphragm that partitions an internal space formed by a valve body and a cover into spaces in which a pressure chamber connected to a connection port, an air inlet and an air outlet are formed, respectively. The valve cup is assembled to the diaphragm. The coupling member fixes the diaphragm and the valve cup. The spring elastically supports the diaphragm in the pressure chamber, wherein a side wall of the valve cup has a sectional shape concave toward the center of the valve along the entire circumference thereof so that a side portion of the diaphragm is deformed toward the center of the valve while being adhered closely to an outer surface of the side wall of the valve cup in a state in which an edge portion of the diaphragm is fixed by the valve body and the cover.

Description

technical field [0001] The invention relates to an anti-surge valve for a vehicle. More specifically, the present application relates to an anti-surge valve for a vehicle, which can prevent diaphragm damage due to stress concentration during operation, and can prevent engine operating conditions due to diaphragm damage during vehicle operation. Conditions of disorder and loss of power. Background technique [0002] Typically, a turbocharger for supercharging intake air supplied to an intake manifold is mounted on a compressed natural gas (CNG) engine that uses CNG as fuel. The turbocharger has a structure including a compressor and a turbine, which are coaxially connected to each other. [0003] In the turbocharger, the compressor is connected with the intake pipeline, and the turbine is connected with the exhaust pipeline. If the turbine is rotated by the pressure of the exhaust gas discharged from the engine through the exhaust line, the compressor coaxially connected t...
