摘要:
A modular device for compressing gaseous fluid includes a first stage with a first hot chamber, a second cold chamber, a piston assembly separating the first and second chambers inside a main enclosure, a regenerative heat exchanger establishing a fluid communication between the first and second chambers by at least a first communication line, and optionally third and fourth chambers separated by a fixed divider separating the third and fourth chambers placed in communication by a second communication line. It thus includes a compressor with one, two, or four stages based on a modular architecture with common components.

The main feature of the 'DOUBLE EXPLOSION PISTON' consists in the fact that it can also produce intermittent explosion that allows the obtaining of a higher engine torque for various revolutions. The system permits the efficient filling of the two combustion chambers of the 'DOUBLE EXPLOSION PISTON' so that while one piston produces the explosion, the other one is loading, ensuring constant pressure upon the engine torque. The existence of the intermediate segment inside the cylinder of the 'DOUBLE EXPLOSION PISTON' makes the bottom piston work in a four-stroke cycle also, ensuring identical performances as the upper piston. The fuel allocation to the bottom piston can be piloted to achieve an optimizing of the engine torque, meaning the strokes can coincide or can be in contrast.

A process for preparing a water-absorbent resin, which can reduce the amount of back flow of a liquid to be absorbed and, at the same time, can enhance the diffusibility of the liquid to be absorbed. The process comprises conducting the polymerization of a water-soluble ethylenically unsaturated monomer in the presence of a water-absorbent resin having a water absorption rate different from that of the water-absorbent resin prepared by the polymerization of the above monomer. According to a preferred embodiment, the polymerization is carried out by reversed phase suspension polymerization.

A thermally powered engine which obtains energy from a closed heat transfer loop. The engine has two power cylinders (22, 24). A piston (50, 56) is reciprocally mounted within each cylinder and divides the interior space of each cylinder into two portions (60, 61, 64, 65). A piston rod (52, 58) is affixed to each piston and extends through the upper closed end of each cylinder. A flexible diaphragm (68, 70) is mounted in the lower portion of each cylinder and with the lower closed end of the cylinder forms a power chamber (164, 166). A fluid fills the upper portion of both cylinders. A passageway (78) between the cylinders permits the fluid to act as a free piston causing the piston of the cylinder in its exhaust stroke to force refrigerant from its power chamber to the condenser of the heat transfer loop. Refrigerant from the evaporator of the heat transfer loop flowing into a power chamber forces the piston upward during the pistons power stroke.

Zur Vereinfachung von Konstruktion und Herstellung einer Brennkraftmaschine mit oberen doppeltwirkenden Kolben 4, die in einer oberen Reihe unbeweglicher Zylinderblöcke 1 mit rechten und linken Zylinderköpfen 2, montiert sind, sind die oberen doppeltwirkenden Kolben 4 durch obere Glieder 7 und obere Gelenke 8 mit den oberen Enden von Schwinghebeln 9 verbunden, während die unteren Enden der Schwinghebel 9 durch untere Gelenke 10 und untere Glieder 7' mit unteren doppeltwirkenden Kolben 4' verbunden sind, die in einer unteren Reihe unbeweglicher Zylinderblöcke 1' mit rechten und linken Zylinderköpfen 2', 3' montiert sind. Die Schwinghebel 9 weisen unbewegliche Stützen 11 auf. Zwischen diesen unbeweglichen Stützen 11 und den oberen Gelenken 8 sind Zwischengelenke 12 angeordnet, die mit Schubstangen 15 verbunden sind. Die Schubstangen 15 sind durch Knie 16 mit Stützen der Kurbelwelle 17 verbunden. Die unbeweglichen Stützen 11 und die Stützen der Kurbelwelle 17 sind starr mit dem Gehäuse 18 verbunden.
摘要:
The object of the present invention is to provide a fluid rotary machine in which dead spaces can be reduced as much as possible even if the machine is enlarged by arranging rotary valves directly behind cylinder chambers. The fluid rotary machine in which first and second double-headed pistons (7, 8) intersecting within a case body (1, 2) move linearly back and forth within cylinders (16) due to the hypocycloid principle along with rotation of shafts (4a, 4b) and in which intake and exhaust cycles are repeated in chambers (22), wherein cylinder heads (17) for closing the cylinder chambers (22) are each provided with rotary valves (19) which are rotated by drive transmission from the shafts (4a, 4b) and which are provided with intake holes and discharge holes (19b) alternately communicated with the cylinder chambers (22) via communication channels (20a, 20b), and the rotary valves (19) intersect longitudinal axis of the opposing pistons (7, 8) and are capable of rotating parallel with output axil lines.
