CRYOGAS PUMP |
摘要 |
To improve a cryogas pump, in particular a cryogas pump for cryogenic hydrogen fit for use in vehicles, comprising a cylinder housing and a piston which forms with the cylinder housing a first compression space for the cryogenic gas and which is mounted with a first piston section adjacent to the first compression space by a gas film in the cylinder housing such that owing to its dimensions it can be constructed so as to be fit for use in vehicles, with the shorter piston length requiring less cooling of the piston by the gas film, it is proposed that the cryogas pump comprise a second compression space with which the gas film is in communication and by means of which a flow of gas can be generated in the gas film in the direction of the first compression space.
