Abstract

PURPOSE: For decreasing the sections to be machined and machining works, to make the connecting section of an air supply system of a resin, to equalize said connecting section in size, and to provide said connecting section on the wall section of a check valve chamber on the same axial line as a passage.
CONSTITUTION: A suction pipe 3 is made of a heat resisting resin such as polyacetal resin. The connecting section 3h of an automatic air supply system 6 is provided on the wall section of a check valve chamber 3a on the same axial line of a passage B3d and equalized in size to or made larger than said passage B3d in size. Therefore, undercutting is not required so that a resin can be adopted for making said connection portion 3h. Therefore, said suction pipe 3 has a considerably small number of sections to be machined and so that the manufacture cost thereof is reduced as compared with the ones manufactured of gray cast iron. Further, made of a resin, said suction pipe 3 is sanitary since no rust is generated.
