Abstract
A rotary sliding vane compressor having means for biasing the vanes outwardly. Such means include a resilient element located in the lower portion of the vane slot and engaging a convexly shaped edge on the vane. An improved wear surface on the resilient element at the area of contact with the vane slot provides enhanced service life. The flexing action of the resilient member ensures that the vanes will be moved outwardly during the expansion phase of rotor travel.
Claims4
In a rotary compressor of the type including a cylindrical rotor having a plurality of extensible vanes received in complementary vane slots and a resilient element engageable with the radially inner portion of said vanes and adapted to flex downwardly upon engagement by said vane, said resilient element being a composite structure comprising a metal spring member engageable by the radially inner portion of said vanes, an elastomeric element bonded thereto and a wear surface on said elastomeric element formed of a stretch fabric.
