Claims

[Claims for Utility Model Registration] (1) It has a pressure-receiving wall surface that partitions a pump chamber on its inner surface, and has a suction port and a discharge port for pumped fluid on its outer periphery, and these suction ports and discharge ports are provided inside. The pump head is characterized by having a plurality of recesses formed on the outer surface of the pump head and integrally molded with synthetic resin so as to form reinforcing ribs between the recesses. Pump head structure. (2) The structure of the pump head according to claim 1, wherein the recess and the reinforcing rib are provided point-symmetrically with respect to the center of the pump head, at least in the pressure receiving area of the pump head. (3) The pump head structure according to claim 1, wherein the outer surface of the pump head has a symmetrical shape with respect to a vertical axis or a horizontal axis passing through the center of the pump head. (4) The reinforcing ribs are registered as a utility model and consist of a first set of ribs extending radially from the center of the pump head and a second set of annular ribs concentric with the center. A structure of a pump head according to claim 1. (5) The pump head structure according to claim 1, wherein the reinforcing rib has a substantially uniform width. (6) The structure of the pump head according to claim 1, wherein a ball valve device is provided at each of the suction port and the discharge port of the pump head. (7) The structure of the pump head according to claim 6, wherein a support portion of a ball valve of a ball valve device is integrally formed with the suction port and the discharge port of the pump head.
