Title: Innovations of Harold M Harper

Introduction

Harold M Harper is a notable inventor based in Brooklyn, Michigan, known for his contributions to the field of hermetic compressors. With a total of five patents to his name, Harper has made significant advancements in compressor technology, particularly in enhancing efficiency and sound damping.

Latest Patents

One of Harper's latest patents is titled "Horizontal rotary and method of assembling same." This invention features a hermetic compressor that includes a housing and a compressor subassembly that is resiliently supported within the housing. The compressor subassembly consists of a motor that is drivingly coupled to a compressor mechanism via a shaft. The motor enclosure is connected to the compressor mechanism and encases the motor. A pair of grommets are strategically placed between the housing and the compressor subassembly, allowing for resilient suspension within the housing. The compressor mechanism discharges compressed gas into the housing through an aperture located in the motor enclosure, where a quantity of oil is present in the lower portion of the housing. This design ensures that the discharge gas, exiting through the aperture, is urged through the oil, forming a sound-damping foam. Additionally, the patent describes a method for assembling the rotary compressor, which includes aligning a stator-rotor air gap prior to the assembly process.

Another significant patent by Harper is the "Suction muffler," which features a hermetic compressor equipped with a suction muffler positioned opposite the suction inlet tube. This design incorporates a funnelled inlet port on the muffler that allows for semi-direct refrigerant flow, enhancing motor cooling and overall compressor efficiency. The internal structure of the suction muffler, including baffle walls and a standpipe, creates an increased resonator effect, optimizing refrigerant throughput.
