    Abstract: A rotor structure is disclosed for a fluid compressor of the character having a pair of complementary, intermeshing rotatable rotors for transferring and compressing a fluid from an inlet into the compressor to an outlet from the compressor. The rotor includes helical land and intervening helical groove means for intermeshing with complementary helical land and groove means of a complementary rotor. The helical land and groove means includes a first portion having a first constant helix angle and a second portion having a second constant helix angle which is different from the first helix angle. The two helical portions are disposed on shaft means and meet in a transition area intermediate the opposite ends of the shaft means and in which area the lands and grooves are disposed in mating relationship. One of the helical portions is integral with the shaft means, and the other helical portion is defined by a separate component adapted to be mounted on the shaft means and suitably interconnected with the one helical portion.

    Abstract: A speed control arrangement is disclosed for an engine driven fluid compressor. The engine includes a throttle valve by which the engine speed and accordingly the compressor speed is variably regulated. A pressure sensitive device is connected to the compressor to sense compressor output pressure and includes a component having a mechanical displacement proportional to compressor output pressure. Displacement of the component is imparted to the throttle valve through an improved actuator arrangement which permits the pressure sensing device to be selectively mounted relative to the throttle valve and other than directly on the engine or in precise alignment with the throttle valve actuating arm.

    Abstract: An improved blade or vane structure is provided for a rotary, vane-type fluid compressor. The vane has a solid body of a metal having a low density and a high heat conducting capacity. The metal body is coated with an abrasion-resisting coating which has voids therein between the outer surface of the coating and the vane body. The voids are filled with plastic material to strengthen the coating against collapse in response to forces imposed on the vane during operation of the compressor. An outer coating of self-lubricating material may be bonded to the outer surface of the abrasion-resisting coating.
