Abstract
A pump for conveying a medium having a suction-side inlet, a pressure-side outlet, a suction chamber, a conveyance housing. The conveyance housing having a pressure chamber in which there is a prevailing pressure chamber pressure, and a carrier shaft arranged in the conveyance housing on which a transport element is arranged for conveying the medium along a direction of conveyance from the suction chamber into the pressure chamber. A pressure disc is arranged in an axially fixed manner on the carrier shaft, wherein one side of the pressure disc is fluidly connected to the pressure chamber and exposed to a compressive force acting in the direction of conveyance.
Claims18
A pump comprising:
- a suction-side inlet;
- a pressure-side outlet;
- a suction chamber;
- a conveyance housing comprising a pressure chamber, wherein the pressure chamber operates at a first pressure;
- a first carrier shaft and a second carrier shaft positioned in the conveyance housing;
- a first transport element connected to the first carrier shaft, and a second transport element connected to the second carrier shaft, wherein the first and second transport elements are configured to convey a medium from the suction chamber into the pressure chamber;
- and
- a first pressure disc and a second pressure disc, wherein the first pressure disc is axially fixed to the first carrier shaft and the second pressure disc is axially fixed to the second carrier shaft, wherein a corresponding first side of the first pressure disc has a first base body and a first shoulder and a corresponding first side of the second pressure disc has a second base body and a second shoulder, wherein the first and second base bodies and the first and second shoulders are fluidly connected to the pressure chamber and exposed to a compressive force acting in a direction of conveyance, wherein the first shoulder is axially offset from the second shoulder, and the first and second shoulders radially overlap in an overlapping region.

A pump comprising:
- a suction-side inlet;
- a pressure-side outlet;
- a suction chamber;
- a conveyance housing comprising a pressure chamber;
- a first carrier shaft and a second carrier shaft positioned in the conveyance housing;
- a first threaded fluid transport connected to the first carrier shaft, and a second threaded fluid transport connect to the second carrier shaft, the first and second threaded fluid transports fluidly connected to the suction chamber and the pressure chamber to convey a fluid from the suction chamber into the pressure chamber upon rotation of the first and second threaded fluid transports;
- and
- a first pressure disc arranged with the first carrier shaft extending therethrough and a second pressure disc arranged with the second carrier shaft extending therethrough, such that a first side of the first pressure disc comprises a first base body and a first shoulder and a corresponding first side of the second pressure disc has a second base body and a second shoulder, and wherein the first and second base bodies and the first and second shoulders are fluidly connected to the pressure chamber and exposed to a compressive force, wherein the first shoulder is axially offset from the second shoulder, and the first and second shoulders radially overlap in an overlapping region.
