Title: Larry J DeHemmer: Innovator in Pressure Regulation and Pump Design
Introduction
Larry J DeHemmer is a notable inventor based in Plymouth, MN (US). He holds 2 patents that showcase his innovative contributions to the fields of pressure regulation and pump design. His work reflects a commitment to enhancing functionality and efficiency in industrial applications.
Latest Patents
One of his latest patents is a Non-degrading Pressure Regulator. This device is specifically designed for use with materials that are prone to degradation, such as metallic paints. The construction of the pressure regulator allows for the maintenance of laminar flow throughout the device. A circular disk is positioned at a variable distance from the upper side of the pressure reducing chamber, leading to annular spaces around the stem of the disk. The clearance is engineered to ensure laminar flow is maintained.
Another significant invention is the Diaphragm Pump. This double-diaphragm pump is molded almost entirely out of plastic and features externally-accessible and serviceable check valves. These valves do not require significant disassembly of the pump for maintenance. The diaphragm is crafted from a uniform thickness of material, with convolutions equally disposed on either side of the angle of elevation of the unstressed diaphragm. The pump is designed for mounting on top of a barrel or drum, featuring radiused feet that fit snugly against the rim. The air valve is equipped with U-cup seals in the housing, and the spool moves in a manner that enhances the pump's operational efficiency.
