    Abstract: Pulse tube coolers and Gifford-McMahon coolers are used to cool nuclear spin tomographs and cryopumps. To supply cooled working gas, gas compressors and in particular helium compressors are used with rotational or rotary valves. The rate at which compressed helium is introduced into the cooling device and let out again lies in the range of 1 Hz. A problem of conventional screw or piston processors is that oil from the compressor mixes with the working gas and thus contaminates the cooling device. By providing a second compressor stage, a common pump device can be used to pump in both directions, which results in a two-stage compressor device. The working gas is compressed in each flow direction of the working liquid, in one flow direction in the first compressor stage and in the opposite flow direction in the second compressor stage. Thus, the efficiency of the compressor device is improved.

    Abstract: A pneumatically operated reciprocating pump comprises two opposed pumping chambers, in each one of which a respective flexible bellow slides under the control of a pneumatically operated shuttle valve capable to alternatively let a gaseous fluid in one of the two chambers for expanding the respective flexible bellow, each one of the two chambers being connected to at least one respective suction valve and to at least one respective delivery valve. Each delivery valve is provided with a compensating elastic means capable to compensate variations of rate of fluid that is pumped by the respective chamber. The pneumatically operated shuttle valve comprises a shaped spool sliding between two limit positions within a perforated cylinder, which shuttle valve is connected, for each chamber, to one or more delivery ducts and to one or more ducts for respectively letting and discharging gaseous fluid in and from the respective chamber.

    Abstract: A method and apparatus for producing compressed air includes sealing air in a container capable of reducing its volume by external hydraulic pressure. A weight having a larger specific gravity than water is attached to the container to sink the container deep under water. Compressed air is produced when the volume of the container is reduced by hydraulic pressure, and is transferred into a recovery vessel connected to the container via a check valve. The weight is then separated from the container use and cause the container to float on the water by the action of buoyancy. The compressed air can then be recovered from the recovery vessel.

    Abstract: A method and apparatus advantageously using the shapeless and flowing characteristics of a fluid. The fluid is contained with a suitable film chamber having a given shape; a frame or the like may be used as a supporting means for the chamber. The frame-shaped sack is repeatedly filled and exhausted with a fluid; upon being filled with fluid, it is inflated; upon the fluid therein being exhausted, it becomes deflated. A hollow chamber is supported with a film sack by repeatedly filling and exhausting fluid therefrom so as to have the hollow sack inflated and compressed. By using this method, the hollow sack is used as a pump for pumping a fluid therefrom.
