Title:

Document Type and Number:
WIPO Patent Application WO/2005/085639
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a reciprocating pump structure enabling the easy attachment/detachment of a pump head part to and from a pump drive part. [MEANS FOR SOLING PROBLEMS] Recessed and projected parts are formed in the pump head part and on the pump drive part so as to be fitted to each other, and the narrowed part of a foot part is locked to an approximately U-shaped cutout part formed in a connecting slider. Accordingly, the pump head part is allowed to slide relative to the pump drive part. Thus, since the pump head part can be easily attached to and detached from the pump drive part, the pump head part is made disposable.
