Title
(EN) A New Mechanism for Fluid Power Transmission and Control
Abstract
(EN)
This Mechanism introduces a new concept for rotary valves used in fluid power transmission and control. It transforms the rotary motion precisely to axial straight motion. It can also be used as an actuator.There are two sensitive chambers at the ends of the spool. Four helical grooves operate in axial symmetry. The rotary motion of the helical groove chages the connections/distribution between ports and chambers,thus forces the spool to slide to a balanced position.
