Claim:
An oil-cooled compressor comprising: a compressor body including a rotor chamber; a discharge path extending from a discharge port of said compressor body; oil separating means disposed in said discharge path; an oil feed path for communicating said oil separating means to an oil feed portion of said compressor body so as to feed oil separated by said oil separating means to said compressor body, said oil feed path being branched at an intermediate position thereof into a first feed path portion connected to supply the oil to a rotor chamber of said compressor body and a second feed path portion; opening/closing means interposed in said first feed portion; pressure detecting means for detecting a discharge pressure, said pressure detecting means being disposed in said discharge path; and control means for controlling opening and closing of said opening/closing means on the basis of a relation between the discharge pressure detected by said pressure detecting means and a predetermined pressure value.
