Latest Patents

Among Kenneth's most recent innovations are the Pilot Operated Hydraulic Control Valve and the Low Leakage Orifice-Controlled Poppet Valve.

The **Pilot Operated Hydraulic Control Valve** features a spool-type pilot valve member coupled to the main valve member using a pair of springs. This unique design allows both pilot pressure forces and spring forces to act on the main valve member. The damping chamber, enclosed by the main valve member and its housing, is equipped with a damping orifice that connects to the pilot pressure chamber, effectively reducing vibrations.

The **Low Leakage Orifice-Controlled Poppet Valve** incorporates a pilot poppet pressure balancing arrangement to prevent fluid leakage between the valve's inlet and outlet. This innovative valve includes a pin that slides within a passage in the main valve member, facilitating a seamless balance of pressure. An annular clearance upstream of an orifice, which is smaller than the orifice's diameter, ensures optimized performance while maintaining leak-free operation.
