Document Type and Number:
Japanese Patent JP7183511
Kind Code:
B2
Abstract:
A rotary pump comprising a housing (1) defining an annular chamber with inlet and outlet ports (12;11) spaced apart around the chamber, a flexible annular diaphragm (3) forming one side of the chamber spaced opposite an annular wall of the housing (1), the diaphragm (3) being sealed at its edges to the housing (1), a partition (13) extending across the chamber from a location between the inlet and outlet ports (12;11) to the diaphragm (3). The diaphragm (3) is configured to be pressed progressively against the opposite wall of the housing (1) to force fluid drawn in at the inlet port (12) on one side of the partition (13) around the chamber and to expel it at the outlet port (11) at the other side of the partition (13). The outer face of the annular diaphragm (3) has a trough (40) at the part of the diaphragm (3) which faces the inlet port (12) and/or at the part of the diaphragm 3 which faces the outlet port (11).
