Abstract (en)
[origin: DE19839233A1] The cylinder can be operated with suction and pump strokes, sucking fluid into the cylinder and then pumping it out. The piston can be sealed against the cylinder wall by components containing polymer. Fluid is sucked into the cylinder by at least one suction valve formed as a check valve. The piston is driven in the cylinder hydraulically, pneumatically or by a crank drive.
