| 108 | Fluid System for Oscillating-Piston Engines | US12278627 | 2007-02-09 | US20090151683A1 | 2009-06-18 | Arnold Wagner |
| The fluid system is intended for an oscillating-piston engine (100) which has at least two double-armed oscillating pistons (4) arranged in a spherical housing (19) and revolving together about an axis (23) of revolution arranged in the housing centre, wherein the oscillating pistons, when revolving, mutually perform reciprocating oscillating movements about an oscillation axis (24) perpendicular to the axis (23) of revolution, and guide members (5) attached to at least two pistons (4) engage in at least one guide groove (17) formed in the housing (19) and serving to control the oscillating movements. The fluid system (70) comprises at least one central feed opening (1), lying in the vicinity of an end of the axis (23) of revolution, for a fluid, continuous cavities and/or bores (10) in the pistons (4) for the fluid, and a fluid discharge on the outer side (3) of the respective piston. A rotation of the pistons (4) about the axis (23) of revolution causes a pressure difference which acts as suction at the feed opening (1) and as pressure in the discharge region (16) and thus makes possible a pumpless fluid system or a fluid system which needs only a low supply pressure. The fluid system serves, for example, to lubricate the oscillating-piston engine (100) and—when fuel is used as the fluid—can be supplied with fluid from a fuel tank together with a fuel supply and with cooling of the oscillating-piston engine. | ||||||

There may be a heat exchanger (14) between the separator and the filter There may be a refrigerant dryer group (15) arranged to cool the gas after the liquid has been separated from the gas and before the gas is passed through the filter | ||||||
| 112 | Screw compressor and freezer | US10570880 | 2004-08-17 | US20060285966A1 | 2006-12-21 | Nozomi Gotoh; Masaaki Izumi |
| A screw compressor has a screw rotor (10) and a cylinder (11) having an economizer port (12). The economizer (12) communicates with a compression chamber (13) before closing the compression chamber (13) between the screw rotor (10) and the cylinder (11). Accordingly, the economizer port (12) can be communicated with the compression chamber (13) while the inner pressure of the compression chamber (13) is low. Thereby, the amount of a refrigerant jetted form the economizer can be increased. Cooling effect by a refrigerant is enhanced by increasing the amount of the refrigerant jetted from the economizer port. | ||||||

| 116 | REFRIGERATION SYSTEM EMPLOYING MULTIPLE ECONOMIZER CIRCUITS | US10224759 | 2002-08-21 | US20040035122A1 | 2004-02-26 | Alexander Lifson; Yan Tang |
| The refrigeration system of the present invention includes multiple economizer circuits. After flowing through the condenser, a first path of refrigerant is split from the main path. The refrigerant in the first path is expanded to a lower pressure and cools the refrigerant in the main path in the high pressure economizer heat exchanger. The refrigerant in the first path then returns to the compressor in a high pressure economizer port. A second path of refrigerant is then split from the main path. The refrigerant in the second flow path is expanded to a lower pressure and cools the refrigerant in the main path in the low pressure economizer heat exchanger. The refrigerant in the second path then return to the compressor in a low pressure economizer port. The refrigerant in the main path is then evaporated. The dual stage economizer refrigeration system can be employed with a screw compressor or a scroll compressor. | ||||||

| 118 | Scroll compressor with vapor injection | US10057216 | 2002-01-24 | US06655172B2 | 2003-12-02 | Michael Perevozchikov; Roy Doepker |
| A refrigeration system has a compressor which incorporates fluid injection into one or more of the fluid pockets. A source of fluid for injection into the pockets is attached directly to the shell of the compressor to eliminate the need for having fluid piping between the source of fluid and the compressor. The source of fluid can be a flash tank which increases the capacity and efficiency of the system or the source of fluid can be a heat exchanger which also increases the capability and efficiency of the system. | ||||||
| 119 | Scroll compressor with vapor injection | US10050727 | 2002-01-16 | US06619936B2 | 2003-09-16 | Michael Perevozchikov |
| A scroll compressor incorporates a vapor injection system where, only one vapor injection port is utilized. The single vapor injection port injects refrigerant vapor into two of the initially formed enclosed spaces. The scrolls of the scroll compressor are designed with asymmetric wraps where the non-orbiting scroll wrap extends angularly further than the orbiting scroll wrap. | ||||||
| 120 | Economizer injection ports extending through scroll wrap | US10073511 | 2002-02-11 | US06430959B1 | 2002-08-13 | Alexander Lifson |
| A scroll compressor is provided with economizer injection ports which extend through the wrap of one of the scroll members. Preferably the injection ports are formed through a so-called “hybrid” wrap which has a varying thickness. The other scroll member is provided with grooves in its base plate. The injection of economizer fluid occurs only during a portion of the orbiting cycle when the injection port and corresponding grooves are aligned with each other. However, as the orbiting cycle continues, the injection port will no longer be aligned with the groove. At that point, the injection is ceased. This allows a simple and precise way for valving the flow of the economizer fluid into the compression chambers. | ||||||
