Abstract:
A check valve that can prevent sticking of a valve body and reliably perform an opening and closing action in a check vale having a simple structure and that does not use biasing means on the valve body. A check valve has support pieces of a valve body protruding in the valve body direction on a circular base seat forming an outflow window in the center inserted in a circular groove where a support member (retainer) is formed between an outflow opening and a valve seat and on an open edge of the outflow window formed in the center of the base seat, and the support pieces of the support member (retainer) that support the valve body have linear or planar support parts on the top portion for leveling at least in a radial direction of the base seat.

Claim (Index 2):
The carburetor according to  claim 1 , where in the valve seat is cylindrically shaped with cylindrically shaped inflow and outflow openings formed at opposing ends respectively on each end of the valve seat, the valve seat having an inner diameter larger than the inflow opening and a predetermined length in an axial direction formed between the inflow and outflow openings;\n wherein the valve body is having an outer diameter smaller than the inner diameter of the valve seat, the valve body being moveable in the axial direction within the inner diameter of the valve seat; wherein the plurality of support pieces of the support member protrude from a disk shaped base seat of the support member toward the valve body and are formed centrally on an open edge of an outflow window formed in the center of the disk shaped base seat; wherein each of the plurality of support pieces of the support member supporting the valve body has a linear or planar support part on a top portion for linearly leveling the valve body at least in a radial direction of the base seat.
