<p>PROBLEM TO BE SOLVED: To prevent the deformation of a valve housing and the like caused by high temperature and a variation of temperature in a pump constituted by combining a case, a diaphragm body, a cylinder part and the valve housing and clamp-fixing these parts by a plate spring. SOLUTION: This pump is constituted by combining a case 3, a diaphragm body 14, a cylinder part 11 and a valve housing and clamp-fixing these parts by a plate spring 40 abutting on the side face of each part and the surface of the valve housing. In this case, the plate spring 40 is provided with pressing parts at the portions abutting on the surface of the valve housing, and the valve housing is pressed by the pressing parts to impede the deformation of the valve housing and the like.</p> |
