Принадлежит: Individual

A positive displacement compressor designed for near isothermal compression. A rotor includes a curved sealing portion that coincides with a in an interior rotor casing wall. Liquid injectors provide cooling liquid. A gate moves within the compression chamber to either make contact with or be proximate to the rotor as it turns. Gate positioning systems position the gate in this manner, taking into account the shape of the rotor. Outlet valves allow for expulsion of liquids and compressed gas. The unique geometry and relationship between the parts provides for efficiencies and higher pressures not previously found in existing compressor designs.

The inner peripheral face is formed in such a manner that a number corresponding to the number of flows of the vane cell pump in respect of pump portions are each constructed with an intake region and a pressure region which are passed through by the conveying elements during a rotation of the rotor. Within a pump portion, the radial spacing between the rotation axis and the inner peripheral face increases when viewed in the working rotation direction of the rotor over the intake region in order subsequently to decrease toward the end of the pressure region again. A narrow location, during the passage through which the conveying elements (are displaced radially inward toward the rotation axis to the greatest extent, is located between a pressure region) and a subsequent intake region when viewed in the working rotation direction.

A multi-stage vane-type positive displacement pump used for lifting fluid from oil wells has stages disposed on a common shaft. Each stage has a rotor, a stator, separating vanes, working chambers, a lower cap with inlet ports, and an upper cap with outlet ports. The rotor is in the form of a cam. The stator is formed from two concentric sleeves situated on a base and having an annular gap therebetween. Slots are provided in the inner sleeve and in the base for the movement of the vanes. The vanes are connected to one another by a synchronizing element. The ports are situated opposite the chambers, either side of the vanes. The end faces of the caps of adjacent stages are conjoined to form an annular cavity, which communicates with the gap of the preceding stage. The aim is to increase the reliability of the pump, to simplify the design and to reduce the manufacturing cost thereof while enabling the pumping of fluids with a high content of abrasive particles.

A vane pump that employs one or more less restricted vanes (or looser vanes) within its rotor is described herein. The less restricted vane(s) are configured to radially move outwardly before the remaining vanes during startup. In one case, for example, at least one vane has a different thickness (e.g., thinner) as compared to the thickness of the remaining vanes. In another case, at least one slot has a different width (e.g., wider) as compared to the width of the other slots. The less restricted vane facilitates a cold start in highly viscous oil by allowing easier radial displacement and thus earlier initial build-up of pressure in the pump. The pump may be used with an engine or transmission. 1. A vane pump comprising:an inlet for receiving fluid from a source;an outlet for delivering pressurized fluid to a system therefrom;a pressure chamber cam having an internal space defined by an inside surface and communicated to the inlet and outlet;a rotor rotatably received within the internal space of the pressure chamber cam, the rotor having a plurality of radial slots and a plurality of vanes received and movable within respective radial slots radially towards the inside surface of the pressure chamber cam; anda drive shaft connected to the rotor for rotating the rotor to cause the vanes to draw lubricant in from the inlet and pressurize the lubricant for expelling out through the outlet;the rotor having the radial slots thereof communicated to the pressurized fluid to bias the vanes radially outward therefrom using the fluid pressure;wherein, for at least one of the plurality of vanes, a distance between an outer face of the at least one vane and an inner face of its respective slot is greater than distances between outer faces of the remaining vanes and inner faces of their respective slots to facilitate radially outward movement thereof towards the inside surface of the pressure chamber cam by centrifugal force during initial start-up of the pump.2.
