Abstract
A piston for an air pump has a connecting rod and a sealing valve. The connecting rod has a seat. The seat has a groove and a retaining surface. The groove is defined in an outer surface of the seat. The retaining surface is adjacent to the groove. The sealing valve movably engages the seat of the connecting rod and has an engaging ring and a sealing part. The engaging ring has an inwall which extends into the groove and has an engaging surface facing the retaining surface. The sealing part is connected with the inwall of the engaging ring and sealingly covers the through hole. The sealing valve is not prone to deformation and warpage during the operation of the piston to prevent any operating noise problem.
