| 17 | Pump | JP2915584 | 1984-02-17 | JPS60173381A | 1985-09-06 | SHINOHARA KAZUTERU |
| PURPOSE:To prevent a sealing property from deteriorating due to the wear of a pump casing, by supplying air pressure to an air chamber defined between an inner elastic casing and an outer casing, to keep the contact surface pressure between a rotor and the inner casing constant. CONSTITUTION:A rotor 1 is spirally shaped and housed in an elastic pump casing 2. The pump casing 2 is fitted in an outer metallic casing 3 so that a gap is defined on the peripheral surface of the casing 2 and serves as an enclosed chamber B. The chamber B is connected to an air pressure source through the opening C of the outer casing 2. As a result, the contact surface pressure between the rotor 1 and the pump casing 2 is kept constant, so that the wear of the pump casing does not affect pump performance. | ||||||
