Abstract

PURPOSE:To promote reduction of noise by enveloping the periphery of a pump main unit forming an almost enclosed-state air chamber, in the case of a rotary pump which rotates rotors in a pump casing formed in the pump main unit. CONSTITUTION:A rotary pump, having a pump main unit 1 forming a pump casing 2 in the inside, opens a fluid inflow port 3 and fluid outflow port 4 to the pump casing 2. A gear 6 in a drive side and a gear 7 in a driven side, serving as the rotors, are contained meshing with each other in the pump casing 2. In this structure such as described, a cylindrical air chamber main unit 10 is arranged on a flange part 1A extending to the outer of the pump main unit 1, and this main unit 10 closes its another opening part by a blocking plate 11 providing a clearance H for a cover 5 on the pump main unit. In this way, the pump, partitioning an air chamber A in the periphery of the pump main unit 1, promotes the reduction of noise transmitted to the outside from the pump.
