Latest Patents
Tripp's latest patents include a piston pump with a discharge valve, inlet valve, and misalignment. This piston pump mechanism is designed for use in positive pressure and vacuum pumping systems, capable of pumping various gases such as air, freon, and natural gas. The innovative design incorporates an inlet and discharge valve system that effectively eliminates any unpurged or unswept volume of gas within the pump cylinder during each reciprocating stroke of the pump piston. Additionally, the mechanism features a control spool that floats within the pump head, allowing for optimal seating engagement of the discharge valve around the entire periphery of the cylinder.
Another significant patent is the rotary cutting assembly with mechanical line feed. This invention provides a vegetation cutter that employs a revolving flexible non-metallic line as a cutting member. It includes a mechanism for mechanically feeding out additional line to replace lengths that may break during operation. The design features a rotatable spool for storing extra line, with a control mechanism that allows for precise feeding of the line only when necessary.
