摘要： Non-contacting cartridge shaft seals prevent leakage loss of process gases in an “oil free” rotary screw compressor or blower, while simultaneously preventing ingress of lubricating oil to the pumping chamber, allowing the compressor/blower to generate process pressure differentials without oil contamination. A compact unitized seal cartridge assembly is provided in the end plates of the pump housing. One of the rotor shafts extends through an aperture in the end plate or housing, between the pumping chamber and oil-lubricated gear/bearing cases. Internal elements have the ability to self-align radially achieving essential concentricity with shaft rotational axes. The rotor shafts or sleeves non-contact relationship during operation allow increased ranges of shaft rotational speeds. Air seal elements restrict flow of process air from the pumping or compression chamber, and oil seal elements with a directional spiral groove on the inside diameter prevent the leakage of lubricating oil to the process or atmosphere.

摘要： A system for removing material with a high velocity jet of working fluid comprises an ultra-high pressure pump having an odd numbered plurality of composite fluid cylinders disposed radially outwardly of an axis of rotation of an eccentric crank. Each composite cylinder includes an inner low pressure cylinder and an outer high pressure cylinder coaxially aligned therewith and the longitudinal axes of the composite cylinders are spaced equilaterally around the crankshaft axis of rotation in a common radial plane. A low pressure piston is mounted in each low pressure cylinder for reciprocation between inner and outer ends and each low pressure piston is interconnected with the crankshaft eccentric to reciprocate on sequential pressure and exhaust strokes during each revolution of the crankshaft. Each high pressure cylinder includes a high pressure piston interconnected with a respective low pressure piston and adapted to reciprocate therewith. A high pressure valve system is provided for each cylinder including an inlet check valve for introducing working fluid into the high pressure cylinder upon successive exhaust strokes thereof. The valve system further includes an outlet check valve for each high pressure cylinder for expelling working fluid under ultra-high pressure as the high pressure piston moves on a pressure stroke.

摘要： A system for removal of workpiece material with a high velocity jet of working fluid, comprising an ultra-high pressure pump including a plurality of low pressure fluid cylinders and a plurality of high pressure cylinders longitudinally aligned with and adjacent the outer end of each low pressure fluid cylinder and having a high pressure piston reciprocally mounted therein and interconnected to reciprocate with a low pressure piston in an adjacent low pressure cylinder. High pressure valves are provided for each high pressure cylinder including an inlet check valve and an outlet check valve for releasing said working fluid under high pressure. A high pressure manifold is interconnected to the outlet check valves and a conduit carries the high pressure working fluid to a high velocity jet forming nozzle. A suction hood surrounds the nozzle for carrying away material debris removed from the workpiece and a liquid spray is provided to wet the debris removed by the jet and confine the material for pick-up by the suction hood.

摘要： A seal component which establishes a seal between a rotating shaft and a housing includes an annular face and an axially extending tubular elastomeric bellows. The geometric configuration of the bellows allows it to buckle, exert a substantially uniform axially force over a wide operating range, and be used without reinforcing members.
