OSTI ID:6954969
In a rotary compressor for a refrigeration system, an injection cooling arrangement is described comprising: a compression bore defined by a compression cylinder, a top planar portion and a lower planar portion; a roller operably disposed within the cylinder bore for eccentric rotation therein; a vane slot within the compression cylinder; a sliding vane slidingly received within the vane slot; means for biasing the one vane against the roller thereby defining a high pressure chamber and a low pressure chamber; an orifice in the lower planar portion leading to the high pressure chamber of the cylinder bore, the orifice being opened and closed by the roller as the roller rotates within the cylinder bore; and a liquid refrigerant inlet path connecting together a liquid refrigerant supply and the orifice.
