Design of a High-Speed Crank-Slider Valve for use in Hydraulic Switch-Mode Systems with Experimental Validation in a Pressure Boost Converter Circuit
Anne Carter
The valve architecture consists of a dual spool design actuated from a common crankshaft
by two 4-bar crank-slider mechanisms. The valve completes two switching cycles per
crank-shaft revolution and the variable duty cycle is achieved by phase shifting one crank arm
relative to the other. The valve design constraints included a switching frequency up to 120 Hz, a
transition ratio of 5% of the cycle period, and a flow rate of 22.8 lpm at a 0.6 MPa pressure drop.
The experimental validation of the valve consisted of two quasi-static tests and one transient test.
The first test determined the valve effective area as a function of crank-shaft position.
