  • Patent number: 11192200
    Abstract: A system, in one embodiment, may include a chassis, an engine coupled to the chassis, a generator coupled to the engine, and a rotary screw compressor coupled to the chassis independent from the engine. The engine may be configured to drive both the generator and the rotary screw compressor. A method, according to another embodiment, may include isolating a rotary air compressor from an engine and a generator in a common chassis. The isolating may include separately mounting the rotary air compressor and the engine with a resilient or distance adjustable connection in between. The isolating also may include resiliently mounting the engine, or the rotary air compressor, or both.
    Type: Grant

  • Patent number: 9000328
    Abstract: A system, in one embodiment, may include an engine, a compressor coupled to the engine, and an oil fill assembly coupled to the compressor. The oil fill assembly relocates an oil fill location from a bottom region of the compressor to a top region of the compressor. A system, in other embodiments, may include a compressor retrofit kit. The kit may include a first tube configured to couple with a drain or an existing oil fill disposed in a base region of a compressor. The kit also may include a second tube coupled to the first tube, wherein the second tube is configured to couple with a vent in the compressor. The kit may include a relocated oil fill section coupled to the first tube, the second tube, or a combination thereof. A system having a compressor retrofit kit attached to the case of the compressor is also provided.
