Title: Jack F Fritchman: Innovator in Refrigeration Technology
Introduction
Jack F Fritchman is a notable inventor based in Cullman, Alabama. He has made significant contributions to the field of refrigeration technology, holding a total of 7 patents. His innovative designs have improved the efficiency and functionality of refrigeration compressors.
Latest Patents
Among his latest patents is the Hermetic Refrigeration Compressor. This invention features a single horizontal cylinder and a unique lubrication arrangement that includes a recess on the cylinder block. This recess collects oil that drains from the lower end of the motor, with a supply passage extending downward to open into the cylinder bore near its midpoint. The piston is designed with an elongated shallow groove that connects to the passage during a major portion of the piston stroke, allowing it to receive oil from the recess. Additionally, drain passage means are provided on the piston to regulate the flow of oil out of the groove.
Another significant patent is the Compressor Head and Suction Muffler for Hermetic Compressor. This design utilizes separate cylinder head members for the discharge and suction plenum chambers adjacent to the discharge and suction valves. The two cylinder heads cover a substantial area of the valve plate at the end of the cylinder carrying the valves. The discharge cylinder head is made of metal, while the suction cylinder head is constructed from a plastic material with low thermal conductivity to minimize heat transfer between the discharge and suction plenums. The suction cylinder head is designed as a unitary member, incorporating passages and a portion of the suction muffler, secured in place by a single fastening member.
