Abstract

In a rotary type air compressor comprising a recycling circuit for the air provided with a check valve (29) operatively connected to a fluid actuated control cylinder having a piston member (28) operatively subjected to the vacuum in the intake chamber (13) of the compressor and to the oil pressure in the control cylinder (20) of the intake valve (15) of the compressor, and means (38, 39) connected to said piston member (28) for controlling the air-flow recycled to the intake chamber (13).
