Summary:PURPOSE: A low noise return valve of an LPI vehicle is provided to suppress floating noise by reducing flux through a return hole and to prevent noise due to contact during the opening and closing of a flow path. CONSTITUTION: A low noise return valve of an LPI vehicle comprises a plunger(210), a guide(220), and an elastic member(230). The plunger has the shape of a cylinder and has a smaller diameter than the inner diameter of a return flow path(30). The plunger opens and closes the inlet of the return flow path according to the movement along the longitudinal direction of the return flow path. The guide is manufactured in the shape of a hollow pipe and is fixed inside the return flow path. The elastic member is located between the plunger and the guide.
