RESIDENTIAL COMPRESSOR FOR REFUELING MOTOR VEHICLES THAT OPERATE ON GASEOUS FUELS

摘要

A compressor for natural gas is made in a format suitable for mounting on a wall or upright support at a residential location to permit refilling of the gas reservoir of a gaseous-fueled motor vehicle parked at the residence. The wall-mounted appliance has vibration isolation supports to minimize transmission of noise into the residence. It has a ventilation and air circulation system that allows it to test for the presence of flammable gas both leaking from the appliance and present in the adjacent ambient environment, e.g. a garage. A motor speed control system permits operation of the appliance at speeds which are reduced when approaching the final pressure for the motor vehicle reservoir and at speeds which avoid the natural resonant frequencies of the system.
