DEVICE FOR INCREASING THE PRESSURE IN A MEDIUM FLOW

摘要

The invention relates to a device for increasing the pressure in a medium flow, which device comprises two rotation devices (202, 204) wherein in the first rotation device (202) receives a flow of first medium under pressure via its second medium passage (205) and delivers this via its first medium passage (212) such that the rotor shaft (203) of the first rotation device (202) is set into rotation, which rotor shaft (203) is coupled for transmitting rotation forces to the rotor shaft of the second rotation device (204), wherein the second rotation device (204) receives a flow of second medium via its first medium passage (214) and delivers this while increasing pressure via its second medium passage (218).
