| PURPOSE: To reduce resistance of a rotary piston passing through an anchored portion so as to ensure smooth rotation thereof by providing a weakened portion for enhancing elasticity in the anchored portion of an annular diaphragm with a rotary piston arranged inside. CONSTITUTION: A pump 1 has a work chamber 3 in a casing 2. An annular diaphragm 4 is arranged in the work chamber 3, and a rotary piston 5 is arranged in the diaphragm 4. The diaphragm 4 has an anchored portion 12, and the anchored portion 12 is supported between an inlet 13 and an outlet 14. In this case, a plurality of notches 16, 17 opening sidewise with a substantially S-shaped transversal cross section is formed in the anchored portion 12 for enhancing radial elasticity. Thus, it is possible to reduce the resistance of the rotary piston 5 passing through the anchored portion 12 so as to ensure the smooth concentric rotation of the rotary piston 5.

| PURPOSE:To eliminate the possibility of biting-in hairs or the like into rotating parts and prevent the deterioration of the performance of the pump due to foreign materials by a constitution wherein the pump is constituted by a casing and a movable body contacting with one or multiple points of the internal surface of the casing through an elastic film. CONSTITUTION:The elastic film 6 is extended on the internal surface of the casing 2 provided with a suction port 4 and a delivery port 5 and is pushed against the internal surface of the casing 2 by arms 8 equipped with compressible rollers connected to a rotary driving shaft 7. When the rotary driving shaft 7 is rotated, the arms 8, equipped with the compressible rollers, are rotated under a condition that they are pushing the elastic film 6 against the internal surface of the casing 2. In this case, each centers of the casing 2 and the rotary driving shaft 7 are eccentric, therefore, a volume, formed by the casing 2 and the elastic film 6, is different depending upon the position of the casing 2. Then, the action of pump is effected by utilizing the change of the volume. According to this method the performance of the pump will never be deteriorated by the foreign materials. | ||||||

| PURPOSE:To provide a simple and economical structure of vanes, capable of enhancing the performance of a pump or the like, making a resilient vane from a resilient metal plate with its inner end fixed to a bushing and a coating of a rubber or plastics material applied over the surface of said metal plate. CONSTITUTION:A resilient metal plate 9 made of a material such as spring steel or stainless steel having a high strength is buried in each vane 3 made of a synthetic rubber or a plastics material having a proper resiliency, and the inner end of the metal plates 9 are fixed in respective grooves 10 formed in the surface of a bushing 1 around the circumference thereof. The metal plate 9 is extended substantially over the entire region of the vane 3 and formed with through-holes 12 so as to increase the bond strength between the metal plate 9 and a rubber or plastics coating 11. By employing such an arrangement, it is enabled to increase the resiliecy and the strength of the vanes without changing the configuration and increasing the thickness of the vanes. | ||||||

| PURPOSE: To provide pulsation-free pumping action for two pump chambers which are partitioned by a diaphragm in a pump casing by allowing a pair of eccentric wheels to be driven eccentrically with a phase difference of 180° by the shaft of the pump, in the pump casing. CONSTITUTION: A pair of eccentric wheels 14 are fitted around the pump shaft 7 which is axially supported rotatably onto a pump casing 1 through a bearing 8, separated in the axial direction and with a phase difference of 180° in the circumferential direction. Thus, a pair of eccentric wheels 14 are eccentrically driven with a phase difference of 180° by the shaft 7 of the pump in the pump casing 1, and the phases of the suction chamber Pi and the discharge chamber Pe which are formed in two pump chambers partitioned by a diaphragm 24 in the pump casing 1 are diverged by 180°, and the fluid transported under pressure from each discharge chamber Pe is joined, and the pulsation due to the divergence of phase of each fluid by 180° can be dissolved.

| A pump is formed by a housing (10) having a fluid inlet (11) and a fluid outlet (12) and containing a rotor (15) forming with the housing (10) chambers (17a, 17b) that, on rotation of the rotor (15) by a drive, convey fluid from the inlet (11) to the outlet (12) to pump the fluid. A seal assembly (14) is arranged between the outlet (12) and the inlet (11). The seal assembly (14) includes a membrane (21) that contacts the rotor (15) and a flexible resilient spring member (22, 28, 35, 37, 40) that provides a force urging the membrane (21) against the rotor (15). The spring member (22, 28, 35, 37, 40) thus, on rotation of the rotor (15), moves radially relative to the axis of rotation of the rotor (15) and is arranged to provide a force on the rotor (15) via the membrane (21) that is constant and a minimum to maintain a seal between the rotor (15) and the seal (14) for a given outlet pressure of the pumped fluid. | ||||||

| A pump is formed by a housing (10) having an inlet (11) and an outlet (12) for a fluid. The housing (10) contains a rotator (13) provided with at least one surface recess (17a, 17b, 17c, 17d) that forms with an interior surface of the rotor a chamber (18a, 18b, 18c, 18d) that, on rotation of the rotor (13), conveys fluid from the inlet (11) to the outlet (12). A flexible seal (23) is provided on or as part of the housing (10) and is located between the inlet (11) to the outlet (12) to engage the rotor (13) to prevent fluid passing from the outlet (12) to the inlet (11). A second inlet (16) is provided leading to the outlet (12) for the supply to the outlet (12) of a second fluid and the second inlet (16) also supplies the second fluid to the back of the seal (23) to urge the seal (23) against the rotor (13). | ||||||
