Latest Patents
Shaffer holds a patent for a pressure relief valve designed specifically for grease guns. This invention features a flow control handle that supplies lubricant to a grease fitting. The handle includes a flow control valve, a handle extension, and a manual trigger for controlling the flow. A key aspect of this design is the pressure relief valve, which operates to relieve high-pressure grease within the handle extension. This valve is an internally seating pin valve that is spring-biased to a closed position. The valve opens when the trigger is engaged with the valve stem, compressing the spring. Notably, the trigger movement is opposite to that required to open the flow control valve, ensuring that high-pressure grease cannot enter the extension when the relief valve is activated. Shaffer's patent represents a significant advancement in grease gun technology.
