Abstract: A compressor device includes a coolant jacket cooperatively defined by a motor case and an outer motor housing. The coolant jacket includes a radial portion that spans about the motor case in a circumferential direction and an axial direction with respect to the axis of rotation of the motor. The coolant jacket includes an axial portion that spans in a radial direction across an axial end of the motor case. At least one of the plurality of flow passages fluidly connects the radial portion and the axial portion.

Abstract: A turbomachine includes a first housing member having a first journal bearing portion and a first radial control surface. The turbomachine also includes a second housing member with a second journal bearing portion and a second radial control surface. The second radial control surface has an interference fit with the first radial control surface that radially aligns the second journal bearing portion and the first journal bearing portion along a common axis.

Abstract: A compressor device includes a motor cooling system that provides a first flow of a first fluid through a housing for cooling a motor. The motor cooling system includes a first fluid flow section at a first axial position. The first fluid flow section extends in a downstream direction radially with respect to the axis of rotation. Also, the device includes a bearing cooling system that provides a second flow of a second fluid through the housing for cooling the bearing. The bearing cooling system includes a second flow section at a second axial position that is spaced apart axially from the first axial position. The second flow section extends in a downstream direction radially with respect to the axis of rotation. The first flow section and the second flow section are disposed in a heat exchanger arrangement configured to transfer heat between the second fluid and the first fluid.

Abstract: A turbomachine includes a housing assembly having a first housing member with a shroud surface, a bearing housing, and a second housing member. The turbomachine further includes a bearing that supports rotation of a rotating group within the housing assembly. The first housing member has a first axial surface and the bearing housing has a second axial surface that is substantially flush with the first axial surface. The second housing member has a third axial surface facing in an axial direction opposite that of the first and second axial surfaces. The first housing member has a first radial surface and the bearing housing has a second radial surface. The first housing member and the bearing housing are attached to the second housing member. The first and second axial surfaces abut against the third axial surface, and the first radial surface abutting against the second radial surface.

Abstract: A centrifugal compressor may comprise a wheel and a pipe diffuser. The pipe diffuser may comprise an annular pipe diffuser section and at least one cylindrical hole passing through the annular pipe diffuser section for compressing gas emerging from the wheel. The at least one cylindrical hole may have an axis that is slanted at an angle A relative to a plane that is orthogonal to an axis of rotation of the compressor.

Abstract: A manually actuated liquid sprayer has a ported element selectively movable between a retracted position and an extended position at which the element lies in the path of the spray plume for mitigating the spray. The element has a cylinder with a smooth inner wall defining a turbulence chamber coaxial with the discharge orifice of the nozzle cap to which the element is mounted. A transversely extending perforate wall is located in the cylinder, and has an open port of a size greater than that of the discharge orifice and being coaxial therewith. The element is movable relative to the nozzle cap between the retracted position at which the liquid spray passes through the open port without influence from any portion thereof, and the extended position at which the liquid spray impacts against the smooth inner wall to mix with air in the chamber and passes through the perforate wall to create foam ejected from the element.

Abstract: A trigger pump sprayer has an external cover plate mounted on and parallel to an end wall of the pump body containing the discharge orifice for transverse sliding movement between an orifice covered position at which a first portion of the cover plate overlies the orifice and an orifice uncovered position at which a second portion of the cover having a through opening lies coaxial with the orifice. Guide tracks on said end wall supporting said plate for sliding movement are sloped toward the end wall for camming an inner surface of the first portion of the plate toward the confronting outer surface of the end wall for fluid tightly sealing the orifice closed against leakage in the covered position.

Abstract: A foamer nozzle assembly combines a turbulence chamber with a foam enhancer comprising a plurality of spaced ribs defining uniform openings, the ribs having flat surfaces lying perpendicular to the inner wall of the chamber for further generating foam as the foam bubbles impact against such flat surfaces to further mix with the air in the turbulence chamber.

Abstract: A precompression pump sprayer is primed by the provision of a priming ramp for deflecting the lower end of a poppet valve member at the end of the plunger downstroke for cocking the valve member so as to disrupt its sealing action with the discharge valve seat to thereby permit air to be released from the pump chamber through the discharge orifice and to the atmosphere.

Abstract: A foamer nozzle assembly has dual screens of intersecting strands in spaced sets of strands, the strands of one set being offset relative to the strands of the other set for establishing two turbulence zones as the flow direction of spray particles is deflected when passing through the first screen and as the flow direction of the spray particles is further deflected when passing through the second screen. The screens are located in a cylinder of the assembly which may or may not define a turbulence cylinder depending on the spacing of the screens from the discharge orifice. The screens may be spaced apart a given distance to establish a turbulence zone therebetween.

Abstract: A trigger actuated fluid dispenser for simultaneously dispensing disparate fluids separately stored in separate fluid compartments of a container includes side-by-side pump cylinders receiving side-by-side pump pistons reciprocable simultaneously during each pressure stroke applied by a single trigger lever for separately and simultaneously pumping the disparate fluids along separate discharge paths.
