| 20090148323 | Rotary Machine and Combustion Engine - The present invention relates to a rotary machine that can be employed in different applications such as, for example, a combustion engine or compressor. The invention further relates to an assembly of two or more rotary machines and a combustion engine based on the rotary machine. The machine is substantially composed of a helical screw-shaped rotor connected to an outgoing shaft journal, which screw-shaped rotor rotates in a cylindrical housing. The machine is further provided with rotating chamber dividing bodies whose rotation is synchronised with the rotating screw-shaped rotor. The chamber dividing bodies divide the helical screw grooves into chambers whose volume varies with rotation of the screw-shaped rotor. | 06-11-2009 |
| 20100202909 | FLUID MACHINE AND REFRIGERATION CYCLE APPARATUS - A fluid machine ( | 08-12-2010 |
| 20130022485 | Unified variable displacement oil pump and vacuum pump - A unified variable displacement pump having a housing which includes a fluid pump and a vacuum pump. A portion of the housing is part of the fluid pump, and a portion of the housing is part of the vacuum pump. A shaft extends through the fluid pump and the vacuum pump. A vacuum pump rotor is formed as part of the shaft, and a vane pump rotor is mounted to the shaft such that when the shaft rotates, the vacuum pump rotor and the vane pump rotor rotate, causing the fluid pump to pump fluid and the vacuum pump to generate a vacuum. The vacuum pump and fluid pump are combined into a single component driven by a single shaft. | 01-24-2013 |

| 20140301877 | Pump device for delivering a medium - A pump device having a vane-type pump has a check valve in a fluid duct which leads from a pressure region to an under-vane region. The check valve blocks in the direction of the pressure region, preventing pressure from escaping from the under-vane region into the pressure region during the start-up of the vane-type pump. | 10-09-2014 |
| 20160053761 | Screw Pump - The invention relates to a screw pump having two screws, in which screw pump each screw has a first thread and a second thread. The threads extend in each case from a suction side to a delivery side. The threads are in engagement with one another, with the result that the threads are divided into a plurality of working chambers, the volume of which decreases from the suction side to the delivery side. According to the invention, the threads have two thread turns. Moreover, the invention relates to a screw for a pump of this type. On account of the uniform distribution of mass of the two-turn threads, the pump can be operated at a high rotational speed, with the result that the throughput of the pump is increased. | 02-25-2016 |
| 20160061203 | SCROLL COMPRESSOR - A compressor according to the present disclosure may include a container; a drive motor provided in the container; a crankshaft coupled to a rotor of the drive motor; a first scroll coupled to the crankshaft to receive a rotational force of the drive motor to perform an orbiting movement; a second scroll coupled to the first scroll to form a first compression unit and a second compression unit along with the first scroll; and a vane provided in the first scroll or second scroll to be brought into contact with the other side scroll to form the second compression unit, wherein the first compression unit is carried out in a scroll compression mode and the second compression unit is carried out in a rotary compression mode. | 03-03-2016 |
