摘要：A precompression pump sprayer of the type having main and secondary pump cylinders and pistons have a two-piece main piston assembly comprising a separate piston sleeve element of molded compliant material and a hollow piston stem of molded rigid material affixed thereto. The more rigid stem permits a reduction in its overall height and overall diameter, resulting in a reduction of the overall height of the pump sprayer. The cylinder has an extension in frictional engagement with the separate sleeve element of the main piston assembly for fixing the secondary cylinder thereto.
