Abstract
A valve arrangement comprises a stationary tubular wall with a cover plate defining a housing and an opening in the wall. A second coaxial tubular wall or valve element acts as a closure element for closing the opening with seals acting through axial displacement relative to the stationary wall. This allows for a very compact construction with simultaneous good flow conditions. The valve arrangement can also be directly integrated into a pump housing whereby the use of available space is further improved. The low force expenditure for the closing operation as well as the possibility of continuously controlling the flow for the valve are further advantages.
