  • Patent number: 9644762
    Abstract: A valve assembly includes a sleeve with an inlet and an outlet. A spool is slideably disposed within an interior of the sleeve and is movable along a spool movement axis defined by the sleeve between first and second positions such a flow area between the inlet and outlet is greater when the spool is in the second position than when the spool is in the first position. An aperture plate seats within the sleeve inlet and is axially adjacent to the spool. The aperture plate defines a core flow and a flow-directing aperture to center and straighten a fluid flow entering the sleeve inlet.

  • Patent number: 5198104
    Abstract: A device that reclaims industrial fluids. Solid contaminants are removed from the liquid being reclaimed by a series of increasingly fine filter elements positioned within a filter housing. The substantially solid contaminant-free fluid then enters an evaporation chamber having a design that constrains the fluid to form a thin film atop an evaporation plate at the bottom of the chamber to facilitate evaporation of volatile contaminants. Insert members are positioned within the evaporation chamber to increase the surface area of the thin film to further enhance the removal of the volatile contaminants. The temperature and pressure of the evaporation chamber is controlled by a heating element that is under the control of a temperature sensor. Evaporated volatile contaminants escape the evaporation chamber through a port formed in the head that closes the device. Latches are used to secure the head in the absence of conventional nuts and bolts, and the head screw threadedly engages the evaporation plate.

  • Patent number: 4830745
    Abstract: An oil purifier for removing contaminants, particularly volatile contaminants. Oil enters an inlet, passes through a filter, a felt layer, a plurality of capillaries, and then spreads across an evaporation plate to an oil outlet. The oil is heated as it spreads across the evaporation plate, either by an external energy source or by hot engine oil, causing volatile contaminants to evaporate and be discharged out a second outlet. The gas pressure above the evaporation plate is kept substantially reduced below atmospheric pressure in order to minimize both the required evaporator plate size and the temperature of the oil spreading thereover and yet provide the desired evaporation rate of the volatile contaminants.

  • Patent number: 4443334
    Abstract: An oil reclamation device includes a housing that has an interior divided into at least two areas by a somewhat upright, generally conical vaporization plate. The area which is above the plate is a vaporization chamber at or less than atmospheric pressure. The area which is below the plate is pressurized filter area, usually the pressure is supplied by the oil pump of an engine. The bottom of the vaporization plate has a plurality of dependent heat transfer fins for creating a turbulent and uniform heat transfer from the vaporization plate to the oil. The top of the plate contains a cup terminating holes for transferring oil from the area below the plate into the cup. A covering washer forces oil in the cup to form a thin film. The transferred oil overflows the cup and runs, under gravity, down an oil-confining, helical channel which conically spirals downwardly.
