Gas compressor

A system for compressing and delivering partly cooled gas to a desired location, comprising:

• a tank for storing compressed gas, a platform secured to the tank, a conventional air cooled four-cycle single cylinder internal combustion engine mounted on the platform, a gas compressor mounted on the platform whereby the tank, platform, engine, and compressor form a unit-handled assembly, means drivably connecting said engine to said gas compressor whereby the engine drives the gas compressor, said compressor comprising engine components of an identical air cooled four-cycle single cylinder internal combustion engine including a crankcase assembly, a cylinder attached to the crankcase assembly, a piston, said cylinder having a bore accommodating said piston, crankshaft means connected to the piston, and blower means connected to the crankshaft means for moving aspirated air toward the cylinder, shroud means surrounding the blower means for directing air toward the cylinder, and compressor components including a valve assembly mounted on the upper end of said cylinder for controlling the flow of gas into and out of the bore in response to movement of the piston therein, head means located in superposed engagement with said valve assembly, said valve assembly spacing the head means from said cylinder to form an open space between the head means and said cylinder to minimize the transfer of heat from the head means to said cylinder, said head means having a gas inlet port and a compressed gas discharge port in cooperative relationship to said valve assembly for gas flow control, means to connect the head means to the cylinder and secure the valve assembly therebetween, an after cooler conduit connected to said head discharge port for carrying hot compressed gas from said head means to the tank, said conduit including an arcuate portion disposed in circumambient relation to said blower means in the inlet path of the aspirated air theretoward, and shield means connected to the shroud means centrally of said arcuate portion of the conduit in spaced relation to said shroud means and blower means for confining said aspirated inlet air flow substantially radially inwardly over and around said arcuate conduit portion toward said blower means.
