| 摘要 | A gas pump including a delivery chamber with an inlet and an outlet for a gas; a first housing part with a first sealing surface which at least partially surrounds the delivery chamber; a second housing part with a second sealing surface which at least partially surrounds the delivery chamber, wherein the second housing part together with the first housing part at least partially encloses the delivery chamber; a delivery device which can be moved within the delivery chamber, for delivering the gas; and a pressing device which presses one of the housing parts against the other with a pressing force, such that the sealing surfaces abut each other and together form a sealing join which at least partially surrounds the delivery chamber, in order to seal off the delivery chamber, wherein the second housing part can be moved relative to the first housing part, against the pressing force, in order to be able to widen the sealing join to form a relieving gap through which liquid situated in the delivery chamber can escape. | ||||||
