TLDR
In this article, a combined compressor and pump has two parallel shafts journalled in a housing having a compressible fluid inlet and a compressed fluid outlet, and a cooling jacket circulates within a coolant jacket in the housing and is circulated by the gear pump.Abstract:
A combined compressor and pump has two parallel shafts journalled in a housing having a compressible fluid inlet and a compressible fluid outlet. Rotors are mounted on each of the shafts for forming a roots type compressor and compressing fluid from the compressible fluid inlet. One shaft of the compressor, which forms a supercharger for an engine, is driven by the engine, and the other shaft is driven in synchronization therewith by a pair of meshing gears mounted on the shafts, the meshing gears being constructed so as to form a gear pump. A coolant circulates within a coolant jacket in the housing and is circulated by the gear pump. The heated coolant may be circulated through a closed loop including a heat exchanger and a bypass passage for bypassing the heat exchanger during low temperature operating conditions.read more
