Abstract

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.COPYRIGHT: (C)1983,JPO&Japio
