| 21 | OVERHEAT CONTROL MECHANISM FOR ELECTRICAL VACUUM PUMPS | US13623146 | 2012-09-20 | US20140079568A1 | 2014-03-20 | Martin Tarnowski |
| A vacuum pump connected to a unit where a low pressure is desired to be maintained, is adapted to reduce a rise in its temperature, during extended operations of the pump. A suction channel has a first end connected to a suction port of the pump and a second end connected to the unit. An aperture provided on the suction channel extends to a pre-determined depth with the channel. The aperture is plugged by a fusible material, or a material capable of subliming. As the temperature of the pump rises, the suction channel transfers heat to the plugging layer of the aperture, and the layer melts or sublimes gradually, with the temperature rise. Once the layer has completely melted or sublimed, the apertures aspirate ambient air from the surroundings into the pump, which cools the interior components of the pump, and quickly reduces the pump's temperature. | ||||||

| An oil pump includes: a rotor 3 for actuating a pump action to suck oil in a suction passage 24 from a suction port 27 to supply oil to a delivery passage by way of a delivery port 19; and a flow control valve for returning an excessive oil from the delivery passage to the suction passage 24 as a returning flow of oil by way of a bypass passage 29 when a flow amount of oil is excessive in the delivery passage. A corrosion-proof member 9 having corrosion resistance is disposed at the position which faces to the returning flow of oil in the inner wall surface of at least one of the suction passage 24 and the bypass passage 29.

| 28 | Adiabatic positive displacement machinery | US688266 | 1985-01-02 | US4663938A | 1987-05-12 | Stirling A. Colgate |
| Adiabatic positive displacement gas cycle machinery is designed with explicit control of the heat flow between the gas and the walls. The control is achieved by maintaining near-laminar flow and a small wall area to volume ratio. The most stable near-laminar flow in a cylinder is an axial vortex because of symmetry, and hence the induction port design should establish an axial vortex and a low velocity. Induction and exhaust port designs to achieve this flow are applied to a vane pump, an adiabatic air compressor, a diesel engine, and two and four stroke Otto cycle engines. The gain in thermal efficiency for these designs can be significant, up to a factor of 2, since the largest inefficiency in nearly all positive displacement machinery is imperfect control of heat flow. | ||||||
| 29 | Bush bearing and a scroll compressor including a bush bearing | US14679077 | 2015-04-06 | US09897143B2 | 2018-02-20 | Junchul Oh; Sungyong Ahn; Eunji Hwang; Byeongchul Lee; Seheon Choi |
| A bush bearing and a scroll compressor including a bush bearing are provided. A boss of an orbiting scroll may be inserted into and coupled to a boss coupling groove of a rotational shaft, and thus, an outer circumferential surface of a bush bearing may wholly contact an inner circumferential surface of the boss coupling groove, thereby decreasing wear of the bush bearing. Further, friction loss in the bush bearing may be reduced, and thus, compression efficiency and reliability may be enhanced, noise may be reduced, and material costs may be reduced. Furthermore, despite that the bush bearing is formed in a ring shape and press-fitted to the boss, as the bush bearing may be formed of a plastic material having an ether ketone bonding in consideration of a thermal expansion rate, an elongation, and a press-fit range, the bush bearing may be effectively prevented from being detached from the boss, thereby enhancing a reliability of a compressor. | ||||||

| A pump comprises a rotor arrangement and a stator arrangement. The stator arrangement comprises a first part made from a corrosive resistant material which defines a volume which in use is swept by the rotor arrangement for pumping fluid from an inlet to an outlet of the stator arrangement. A second part of the stator arrangement is made from a thermally conductive material which envelopes the first part so that heat generated in the first part can be transferred to the second part at the interface surface between the two parts. The second part has formed therein at least one duct 80 for conveying a liquid coolant through the second part so that heat can be transferred from the second part to the liquid coolant for cooling the stator arrangement. | ||||||

| 33 | Inner rotor of internal gear pump having convex small circular arc parts | US11721228 | 2005-01-12 | US07572117B2 | 2009-08-11 | Katsuaki Hosono |

| 36 | Electromagnetic reciprocating compressor | US556903 | 1995-11-29 | US5603612A | 1997-02-18 | Michael A. McGrath |
| An electromagnetic reciprocating compressor has a body (1, 2), a piston (10) reciprocating in a cylinder (12) in the body and a piston guide (14) in the form of an insert which is radially located relative to the axis of the cylinder (12) by fitting against a registration surface (25a), the registration surface is on a body part (1) which also provides the internal cylinder surface (12a) of the cylinder. To improve the alignment of the insert (14), the registration surface (25a) and the internal cylinder surface (12a) are formed to their respective final diameters in the same machining operation by reference to a common axis. The piston guide (14) is axially located related to the cylinder (12) by being resiliently clamped between the stator (23) and an end portion (27a) of the body (1, 2) opposed to the stator (23) with a resilient member (27) interposed between the body end portion (27a) and the piston guide (14). | ||||||
| 37 | Electromagnetic linear compressor with rotational bearing between springs | US556901 | 1995-11-29 | US5597294A | 1997-01-28 | Michael A. McGrath |
| An electromagnetic linear compressor has a linearly reciprocating piston (10) biased in one direction by a helical coil spring system. A rotational bearing (40) supports one end of the spring system (20a, 20b). To avoid uneven wear due to forces applied by the spring system, the spring system comprises two helical coil springs (20a, 20b) acting in series to bias the piston (10), and the rotation bearing (40) transmits thrust between the two springs while permitting relative rotation of the two springs about their common axis. The compressor also has a turbine (30) for exerting a unidirectional rotational force to rotate the piston (10) about its axis gradually during operation of the compressor. | ||||||
