    摘要: A description is given of a pump comprising a suction space which is at least partly bounded by a flexible body and which is located between end elements at least one of which can be driven so as to move in a reciprocating manner, a delivery space which surrounds the suction space and around which a housing is provided, and valves provided in the housing and in at least one of the end elements, the valves being constructed such that when the volume of the suction space is increased, a medium is sucked into said suction space, which, when the volume is reduced, flows through one of the valves to the delivery space from which it is expelled when the volume of the delivery space is reduced.
