Abstract: The present invention provides a rotary compressor capable of significantly reducing the loss attributable to mechanical friction. Since an outer rotor 2 is connected via connecting plates 4 to an inner rotor 3, when the outer rotor 2 is rotated by external rotational force, the inner rotor 3 can rotate together with the outer rotor 2 in the same direction. At that time, the rotors 2 and 3 rotate at positions offset relative to each other so that partition pieces 2d on the outer rotor 2 perform circular movement within partition grooves 3b in the inner rotor 3 while turning the connecting plates 4. Thus, the rotors 2 and 3 rotate together, with at least two partition pieces 2d turning all the time along the inner surfaces of the associated partition grooves 3b in a non-contact manner, so that a fluid from an inflow port 1d flows into a space between the rotors 2 and 3 partitioned by the partition pieces 2d and the partition grooves 3b, the fluid being discharged through an outflow port 1e.

Abstract translation: 本发明提供一种能够显着降低由于机械摩擦引起的损失的旋转式压缩机。 由于外转子2经由连接板4连接到内转子3，所以当外转子2通过外旋转而旋转时，内转子3能够与外转子2一起沿同一方向旋转。 此时，转子2和3在相对于彼此偏移的位置处旋转，使得外转子2上的分隔件2d在转动连接板4的同时在内转子3中的分隔槽3b内进行圆周运动。因此，转子 2和3旋转在一起，其中至少两个分隔件2d以不接触的方式一直沿着相关联的分隔槽3b的内表面一直转动，使得来自流入口1d的流体流入转子之间的空间 2和3由分隔件2d和分隔槽3b分隔开，流体通过流出口1e排出。

Abstract: A volumetric machine comprises a cylindrical screw meshing with a pinion-wheel, a low pressure port near one end of the screw, a high pressure port near the other end of the screw, and a control slide axially movable in the bore of a housing in which the screw is rotatable. In one condition, including a series of positions, the slide more or less broadens the high pressure port and thus controls the volumetric ratio of the machine, but covers any threads of the screw which are meshing with the pinion-wheel. In another condition, the slide closes the high pressure port except a stationary port but uncovers some of the threads meshing with the screw, such as to establish a part load with a predetermined volumetric ratio.

Abstract: A capacity control device for a screw compressor provided with a capacity control passage and a slide valve adjusting the opening thereof, wherein the slide valve is driven in a closing direction due to a pressure difference between a high pressure and a low pressure and is moved in an opening direction thanks to function of a spring when the high pressure is balanced with the low pressure, and when the pressure difference between the high pressure and low pressure is lower to cause the slide valve to be open thanks to the function of the spring, the slide valve is moved in the closing direction against the spring by use of pressure in a compression-processing part in the screw compressor, thereby enabling to quickly transit from no load condition to a loaded condition.

The liquid opening is configured such that in response to a driving force a stream of liquid is output from the opening, the stream of liquid forming a liquid blade between the rotor and the stator, gas confined by the stator, the rotor and the liquid blade being driven through the pump along a pumping channel from a gas inlet towards a gas outlet in response to relative rotational motion of the rotor and the stator. A cross sectional area of the pumping channel is configured to increase from the gas inlet to the gas outlet.

Abstract: Multi-chamber Compressor (6, 206, 506) of Mechanical Vapor re-Compression (MVC) and water treatment methods, the compressor bearing independent compression chambers of positive displacement, for heat-pumps, of two main variants: a) reciprocating-rotary motion (6, 206) wherein the compression chambers (7V) are radially arranged cylindrical sectors based on concentric circular sectors of the same angle, with, pistons of radially arranged vanes (20, 220) of respective surface and with the plane of the vanes passing through the axis of the common rotor (14) and the shaft (16) and b) reciprocating-linear motion (506) wherein the compression chambers (52v) are in series arranged cylinders with pistons/vanes (50v) of corresponding circular surfaces and with the plane of the vanes perpendicular to the common shaft (51). In both cases, the shaft (16, 51) and the motor are common to all the vanes (20v, 50v), which follow identical strokes. The surfaces of the vanes (20v, 50v), as well as of the compression chambers (7V, 52v), differ from each other, since each compression chamber (7V, 52v) has its own and independent pair of evaporation (ev, dv, Lv, by) and heat-exchanger chambers/areas (Cv/eCv, 32v/33v, 132v, 54v/53v), said compression chamber exclusively sucks from, compresses and discharges to, and the fluids/vapors being dispensed, are under different thermodynamic state conditions. The stages are independent from each other, the medium-vapor providing the energy of evaporation is produced in the stage itself, and flow rate and compression ratio CR are independently controlled and adjusted in each stage.
