Abstract

Screw compressor with a compression chamber that is formed by a compression housing, in which a pair of meshed helical compressor rotors in the form of a screw are rotatably mounted and with a drive motor that is provided with a motor chamber formed by a motor housing, in which a motor shaft is rotatably mounted. The motor shaft drives at least one of the aforementioned two compressor rotors, where the compression housing and the motor housing are connected directly together to form a compressor housing, where the motor chamber and the compression chamber are not sealed off from one another and where the rotor shafts of the compressor rotors, as well as the motor shaft, extend along axial directions that are oblique or transverse to the horizontal plane.

First claim

The invention claimed is:

1. A vertical screw compressor comprising:
a compression chamber, comprising an inlet and an outlet, that is formed by a compression housing in which a pair of meshed helical compressor rotors in the form of a screws are rotatably mounted; rotor shafts of said meshed helical compressor rotors extend parallel to one another along first and second rotational axes, respectively;
a non-return valve provided at the inlet of the compression chamber;
a drive…
