  • Patent number: 10914172
    Abstract: A hydraulic device comprises a shaft mounted in a housing rotatable about a first axis. A plurality of pistons are fixed to a flange rotatable about a first axis. A plurality of cylindrical sleeves sleeve bottoms and sleeve jackets that cooperate with the pistons to form compression chambers. Rotation of the shaft causes the volumes of the compression chambers. Each piston head forms a sealing line within the cooperating sleeve jacket. Each sleeve jacket has a thin wall and/or is elastically movable with respect to the sleeve bottom such that at a fixed pressure the radial deformation of the sleeve jacket at the sealing line is substantially constant at piston positions ranging from bottom dead center to a position where the distance between the sleeve bottom and the sealing line is less than 50% of the distance between the sleeve bottom and the sealing line at bottom dead center.

  • Patent number: 10519850
    Abstract: An object is to provide a turbine housing with a simple structure whereby it is possible to reduce flow resistance of exhaust gas and improve efficiency of a turbocharger. A turbine housing made by casting has an opening part formed on a hub side of a scroll part, the opening part having a radius R2 which satisfies a relationship R1<R2, provided that R1 is a radial directional distance from an axis of a turbine wheel to a tip of a shroud part and R2 is a radial directional distance from the axis to an inner peripheral edge of a hub-side wall surface of the scroll part. A roughness of a flow-path surface in a region A is smaller than in a region B, provided that the region A is a predetermined range from the tip of the shroud part and the region B is a predetermined range adjacent to the region A, among flow-path surfaces of the shroud part and the scroll part facing a scroll flow path on an outer side, in a radial direction, of the tip of the shroud part.

  • Patent number: 10422226
    Abstract: An airfoil for a turbine engine includes pressure and suction sides extending in a radial direction from a 0% span position at an inner flow path location to a 100% span position at an airfoil tip. The airfoil has a relationship between an axial leading edge location and a span position that is at least a third order polynomial with a generally U-shaped curve having an initial negative slope followed by a positive slope. The positive slope leans aftward and the negative slope leans forward. The curve has a critical point in the range of 30-50% span position at which the curve changes from the negative slope to the positive slope. The curve is generally linear from 55% span to 75% span and has a positive slope that increases at a rate of about 0.0875 inch (2.22 mm) per 1% span, +/?0.04 inch (1.01 mm) per 1% span.

    Abstract: A combination of a chamber wall and the flexible membrane defines a pump chamber in a diaphragm pump. The pump chamber includes one or more internal surfaces that are modified to include a pattern of a pattern of channel surface regions. The channel surface regions provide unobstructed pathways to a respective opening disposed on an internal surface of the chamber wall. For example, as discussed herein, presence of the channel surface regions ensures that the facing of the flexible membrane does not needlessly stick (as a result of residual suction) to an inside surface of the chamber wall during a portion of the pump stroke in which negative pressure is applied to a backing of the flexible membrane. In other words, the channel surface regions distribute relief pressure along the inside surface of the pump chamber wall.

Moment MS of rotational motion is based on selling the product of inertia in the variable-angle direction of the swash plate to decrease the inclination angle of the swash plate from ?a. Moment MF is based on the combined urging force of both springs set so that the inclination angle ?b is positioned at a minimum angle at maximum rotational speed.

    Abstract: An air bearing assembly includes a split bearing with a first portion and a second portion configured to join and form a female tapered section with distal ends of a larger diameter than a joining central portion. A shaft with a male section including distal ends of a larger diameter than a central portion mates with the female tapered section formed by the joined split bearing. In order to provide adequate lubrication, support, and cooling, one or more an passages in the split bearing fluidly communicates a supply of pressurized air to the shaft. The air pressure provides a cushion of air for the shaft to float on during operation.

  • Publication number: 20150004007
    Abstract: A cyclonic elevator tube comprising a manifold which supplies fluid under pressure via an annular transition ring with multiple, circumferentially spaced jet orifices. These orifices are set at inwardly and circumferentially directed compound angles for ejecting vortex jets of pressurized fluid through the elevator, to ultimately cause transportation of fluid material through the tubes. This apparatus comprises: a cylindrical chamber; a plurality of helically shaped venturi tubes spaced around the internal circumference of the chamber; a manifold connected to the inlet ends of the venturi tubes; and a high pressure gas supply connected to the manifold. The helix can be right or left handed and preferably the venturi tubes extend for less than one turn of the helix. The angle that the tangent of the helix makes with the longitudinal axis of the chamber is between 1° and 89°. The internal circumference of the chamber may be larger at the inlet end than at the outlet end.

  • Patent number: 8915727
    Abstract: According to one embodiment, a rotary compressor includes a compressing unit provided with a cylinder having a flared portion to provide a vane groove. In the compressing unit, a piston revolves along a cylinder inner wall, and an operation chamber is formed between the cylinder inner wall and the piston. A vane protrudes from the vane groove into the operation chamber and comes in contact with the annular piston to partition the operation chamber into an inlet chamber and a compression chamber. A spring inserted in a spring hole formed in the back of the vane groove presses the back of the vane. A spring holder pin is inserted in a pin hole located on the outer circumferential side of an end of the vane groove and crossing the spring hole to prevent the spring from coming off the spring hole when the compressing unit is installed in the housing.
