Abstract
A screw compressor including a housing containing at least one rotor for generating a discharge flow in a discharge direction; a diffuser member communicated with the housing to receive the discharge flow, the diffuser extending from the housing in the discharge flow direction, the diffuser having a converging collecting section, a diffuser throat downstream of the collecting section and a diffusing section downstream of the throat, whereby the discharge flow can be collected and diffused in the discharge flow direction.
Claims6
A screw compressor, comprising:
- a housing containing at least one rotor for generating a discharge flow in a discharge flow direction;
- a diffuser member communicated with said housing to receive said discharge flow, said diffuser extending from said housing in said discharge flow direction, said diffuser having a converging flow area collecting section, a diffuser throat downstream of said collecting section and a diffusing flow area section downstream of said throat, and said collecting section, said diffuser throat and said diffusing section all extending in a substantially straight line along said discharge flow direction whereby said discharge flow can be collected and diffused in said discharge flow direction.
A screw compressor, comprising:
- a housing containing at least one rotor for generating a discharge flow in a discharge flow direction;
- a diffuser member communicated with said housing to receive said discharge flow, said diffuser extending from said housing in said discharge flow direction, said diffuser having a converging collecting section, a diffuser throat downstream of said collecting section and a diffusing section downstream of said throat, whereby said discharge flow can be collected and diffused in said discharge flow direction, wherein said housing contains at least a first rotor and a second rotor each of which generates a discharge flow in a discharge flow direction, and wherein said diffuser member comprises at least a first diffuser and a second diffuser each positioned to receive said discharge flow from a respective rotor.
