| A vane pump includes a casing and a rotary unit rotatably held within the casing. The rotary unit includes a base portion with radially outwardly opened slits extending radially with respect to a rotational axis of the rotary unit and vanes slidably fitted in the respective slits. An annular chamber is formed around the base portion within the casing and divided into a plurality of pump chambers by the vanes. Each of the pump chambers has a volume cyclically expanded and contracted during rotation of the rotary unit to discharge the fluid drawn into each of the pump chambers. The casing includes an inlet port through which to draw the fluid into the annular chamber. The inlet port is arranged to face a portion of the annular chamber extending between a middle position and a terminating position of an expanding section in which each of the pump chambers expands. | ||||||

| Electrochemical machining is used to generate the helical lobe profiles of the stator of a progressive cavity pump or motor. A thin, elastomeric liner, of uniform thickness is bonded either to the interior of the stator, or to the exterior of the rotor. Where the elastomeric liner is to be bonded to the interior of the stator, bonding is improved by electrically etching the interior of the stator during the electrochemical machining process to produce a roughened surface. | ||||||

| 28 | Scroll compressor | JP10460089 | 1989-04-26 | JPH02283884A | 1990-11-21 | SHIOZAKI TETSUYA |
| PURPOSE: To reduce the weight of a revolving scroll, to reduce a bearing load, and to improve wear resistance by a method wherein a scroll is formed by an aluminum material, a plated layer is formed on the surface of the scroll by an electrodeposition dispersion plating method in which a sulfamine acid nickel bath added with phosphorus forms a base. CONSTITUTION: In a scroll compressor, laps 3 of a fixed scroll, not shown, and a revolving scroll 2 are engaged with each other to form a compression chamber between the laps 3. In this case, for example, the revolving scroll 2 of the two scrolls is formed by on aluminum material. A plated layer 1 is formed on the surface of each of the lap 3 and an end plate 4 of the revolving scroll 2 by a dispersion nickel lean plating method. Namely, the plated layer 1 is formed by on electrodeposition dispersion plating method in which a sulfamine acid nickel bath added with phosphorus forms a base. This constitution reduces the weight of the revolving scroll 2, reduces a bearing load, and improves wear resistance. COPYRIGHT: (C)1990,JPO&Japio | ||||||

| An ECM method involves the use of a thin hollow electrode assembly that carries the electrolyte within and that is advanced relatively to the workpiece. The small profile of the electrode results in a minimal removal of metal in forming the desired rotor or stator shape. The electrode profile allows significant power consumption reduction or increased machining speed for a given rate of power input. The electrode can be a unitary ring shape or can be made of segments that are placed adjacent each other so that a continuous shape is cut. Not all the lobes of the stator or rotor have to be cut in the same pass. Electrode segments can be used to sequentially provide the desired lobe count in separate passes. The lobe shapes in the electrode can be slanted to get the desired rotor or stator pitch or they can be aligned with the workpiece axis. | ||||||

| A Moineau style stator includes a stator tube having a plurality of rigid helical lobes formed on an inner surface thereof. The helical lobes define a major internal tube diameter that is greater than a pass through diameter of the tube such that the major diameter undercuts the pass through diameter of the tube. A major liner diameter may also be less than the pass through diameter so as to provide a suitable interference fit between rotor and stator. | ||||||
