The present invention relates to a device for producing high-strength COpellets from COsnow, in particular, for a cleaning device for blasting surfaces to be treated with a mixed-flow consisting of a compressed gas and COpellets, including a main compressing device for compressing COsnow for forming COpellets, further including a pre-compressing device for pre-compressing COsnow produced by expanding liquid CO, wherein the pre-compressing device is in the form of a fluid-mechanical pre-compressing device, wherein the pre-compressing device includes an expansion device for producing COsnow from liquid or gaseous COand a pre-compression chamber for receiving and pre-compressing the produced COsnow and wherein the expansion device and the pre-compression chamber are connected to one another in fluidic manner.

Device for producing CO2 pellets from CO2 snow and cleaning device

The invention relates to an apparatus for producing COpellets from COsnow, in particular, for a cleaning device for spraying surfaces to be treated with a mixed stream of a pressurized gas and COpellets, includes a compressor device for compressing COsnow to form COpellets. The compressor device includes a gear compressor. The gear compressor includes at least one compressor wheel which is mounted rotatable about a first rotation axis and has a plurality of compressing elements, and includes at least one intake wheel which has a plurality of snow intakes for accepting COsnow. The snow intakes are configured corresponding to the compressing elements. The intake wheel is mounted rotatable about a second rotation axis and cooperates with the at least one compressor wheel. The intake wheel includes an intake wheel sleeve with an intake wheel sleeve wall.

[object Object]

A motor pump unit for a high-pressure cleaning apparatus has an electric motor and a pump. The electric motor has a motor housing that is surrounded by a cooling housing with an annular space having an annular space inlet and an annular space outlet formed therebetween. The pump has a suction inlet connected to the annular space outlet and a pressure outlet. The liquid to be transported by the pump can be supplied to the annular space inlet. The cooling housing, on its inside, has at least one flow guide rib for guiding the liquid within the annular space. In order to ensure that no liquid can leak out of the annular space even in the long term, the at least one flow guide rib is spaced-apart from the motor housing.
