CARBURETOR PISTON

摘要

PURPOSE:To facilitate manufacture by making the piston of carburetor with synthetic resin while holding the diaphragm between synthetic resin containers and adhering. CONSTITUTION:A flange 2 is molded integrally with synthetic resin over the piston 1 of carburetor. A diaphragm 4 is mounted on the flange 2 then a synthetic resin retainer 3 is mounted thereafter adhesive is injected into a gap 5 between the retainer 3 and the upper portion of piston 1 to fix them. Consequently, the piston body, diaphragm and retainer are jointed firmly to improve the air- tightness while to protect the piston body from crack.
