  • Patent number: 6371731
    Abstract: A multi-stage blowdown valve is provided that uses a single control signal to simultaneously decompress the interstage and the second stage in a compressor system. The valve uses a series of sliding spools located linearly within a single bore to either prevent or allow fluid communication between two isolated passageways each having an inlet port and a discharge port. The valve, when used as a two stage blowdown valve in a multi-stage compressor system, can prevent compressor failure from occurring by ensuring that both the interstage and the second stages are decompressed. not only the interstage.

  • Patent number: 6367489
    Abstract: Apparatus for cleaning and servicing vehicle brakes includes a caster mounted cabinet adapted to hold a small drum of cleaning solvent, the drum having an open top. A telescopic post or conduit extends upwardly from the cabinet to a hollow, hinged swing arm. A sink tray is mounted on the end of the swing arm and has a bottom drain opening that communicates with the hollow swing arm, which in turn communicates with the upright conduit to form drain piping for the sink tray. The outlet of the upright conduit empties into the solvent container in the cabinet. A pump mounted in the cabinet takes cleaning solvent from the drum and delivers it through a hose to a spray gun to be applied to the brakes to be cleaned. The telescoping post and adjustable swing arm allow the sink tray to be located directly under the brakes being cleaned to catch and return the used solvent. The cabinet also has a second basin or sink that drains into the container but can be used for cleaning parts.
