ABSTRACT:
In the preferred embodiment, the invention comprises a sealing arrangement in which an elongated slat-type seal is provided for slidable engagement within the slot of a rotor (such as a Wankel engine-type rotor, or the rotor in a vane-type compressor) and includes a leaf spring for biasing the seal outwardly from the slot to effect fluid sealing externally of the rotor. The leaf spring and seal have special, mutually-engaging keying configurations, and the spring has particularly determined contact points which maintain all possible biasing force therein for the longest service time thereof.
