Title: Innovations of Robert D. Klein

Introduction

Robert D. Klein is an accomplished inventor based in Milton-Freewater, Oregon. He holds a total of 2 patents that showcase his expertise in fluid control technologies. His innovative designs have contributed significantly to the field of irrigation and fluid management.

Latest Patents

Klein's latest patents include a "Pressure Control Valve with Pressure Cycling Control" and a "Rate-of-Flow Control Valve." The pressure control valve features a spool valve design that includes a housing with a spring-enclosing portion and a spool-enclosing portion aligned along a longitudinal axis. This design allows for reciprocal axial movement of the spool, which is equipped with a piston at one end. The stationary bushing supports a bore that receives the control end of the spool, incorporating radially-oriented passages that open into an annular groove. This innovative design effectively seals off the passages when the spool is in a neutral position, ensuring precise control over fluid flow.

The rate-of-flow control valve assembly is actuated based on the velocity of fluid in a conduit. It includes a sensing plate that projects into the conduit, perpendicular to the flow direction, and a sleeve valve located downstream. The flexible rubber sleeve of the sleeve valve adapts to vary the flow rate of the fluid, while a spool valve controller manages the flow into and out of the control chamber based on the movement of the sensing plate.
