Power supply unit for pneumatic massage elements has air compression pump driven by direct current via two control valves controlled by integrated electronics

摘要

The power supply unit has an air compression pump (3) driven by direct current via two control valves (4) controlled by integrated control electronics (5) in a cylindrical operating cycles. The two separate chambers of the pneumatically driven inflatable massage elements are operated in this manner. A pressure sensor (6) may enable the elements to be operated at other than full volume.
