Abstract
A scroll compressor for generating oil-free compressed air, in particular for a compressed air brake system of a lorry, with a drive which is arranged in a housing and is connected to an orbiting displacer scroll which has a displacer scroll bottom and a displacer scroll wall. The displacer scroll wall engages into a stationary mating scroll, with the result that at least one variable compression chamber is formed between the displacer scroll and the mating scroll. A seal element is provided between the displacer scroll and the housing wherein the seal element is fastened in the displacer scroll bottom and seals against a sliding plate which is connected fixedly to the housing. A compressed air brake system with a scroll compressor of this type.
Claims14
A scroll compressor for generating oil-free compressed air comprising:
- a drive arranged in a housing and connected with one or more orbiting displacer scrolls, each displacer scroll having a displacer scroll bottom and a displacer scroll wall,
- wherein the displacer scroll wall engages into one or more stationary mating scrolls, so that at least one variable compression chamber is formed between a respective one of the one or more orbiting displacer scrolls and a respective one of the one or more stationary mating scrolls,
- wherein a seal element is provided between the respective displacer scroll and the housing, and
- wherein the seal element is fastened in a respective displacer scroll bottom and seals against a sliding plate fixedly connected with the housing, wherein a scraping element for stripping oil residues from the sliding plate is fastened in each displacer scroll bottom.
A compressed air brake system comprising:
- a scroll compressor configured to generate oil-free compressed air, the scroll compressor including a drive arranged in a housing and connected with one or more orbiting displacer scrolls, each displacer scroll having a displacer scroll bottom and a displacer scroll wall,
- wherein the displacer scroll wall engages into one or more stationary mating scrolls, so that at least one variable compression chamber is formed between a respective one of the one or more orbiting displacer scrolls and a respective one of the one or more stationary mating scrolls,
- wherein a seal element is provided between the respective displacer scroll and the housing, and
- wherein the seal element is fastened in the displacer scroll bottom and seals against a sliding plate fixedly connected with the housing.
A vehicle having an air brake system comprising:
- a scroll compressor configured to generate oil-free compressed air, the scroll compressor including a drive arranged in a housing and connected with one or more orbiting displacer scrolls, each displacer scroll having a displacer scroll bottom and a displacer scroll wall,
- wherein the displacer scroll wall engages into one or more stationary mating scrolls, so that at least one variable compression chamber is formed between a respective one of the one or more orbiting displacer scrolls and a respective one of the one or more stationary mating scroll,
- wherein a seal element is provided between the respective displacer scroll and the housing, and
- wherein the seal element is fastened in the displacer scroll bottom and seals against a sliding plate fixedly connected with the housing.
