Definitions

  • the invention relates to a compressor, in particular a compressor for cryogenic media, preferably for liquid hydrogen, comprising a compressor chamber surrounded by a cylinder wall in which a compressor piston is moved in a linear manner, a suction valve and a pressure valve, which are arranged in the region of the lower end position of the compressor piston, and a liquid chamber which at least partially surrounds the compressor chamber.
  • cryogenic media is understood in the following to refer to so-called deep cold fluids, in particular liquid hydrogen, liquefied natural gas, liquid nitrogen, liquid oxygen and other liquefied gases.
  • Compressors of this type are sufficiently well known from the state of the art. They all have in common the fact that the medium to be compressed is fed through a spring-loaded suction valve into a compressor chamber, where it is compressed and then removed from the compressor chamber via a spring-loaded pressure valve.
  • the elastic force of the spring used for closing a suction valve (in this case, we are dealing preferably with helical springs) is selected, as a rule, so that a defined closing of the suction valve is achieved; the suction valve is therefore pressed into its valve seat and thereby sealed.
  • the objective of the present invention is disclosing a generic compressor, in particular a generic compressor for cryogenic media, in which the aforementioned disadvantages can be avoided.
  • a generic compressor which is characterized in that the cylinder wall comprises at least one opening that corresponds to the liquid chamber, and at least one opening, via which the gaseous medium can be extracted from the compressor chamber, wherein the openings are located at points on the cylinder wall that are passed by the compressor piston.
  • the compressor in accordance with the invention comprising a high-pressure phase separator and additional embodiments of the compressor, are explained in more detail on the basis of the exemplary embodiment depicted in the FIGURE.
  • FIGURE shows a lateral schematic sectional representation through a possible embodiment of the inventive compressor with a high-pressure phase separator.
  • a compressor chamber R surrounded by a cylinder wall 1 is provided within a compressor housing V:
  • a compressor piston K is moved linearly back and forth and/or up and down within the compressor chamber.
  • the two reversing points of the compressor piston K are referred to in the following as the upper and lower end positions of the compressor piston K.
  • a suction valve S which is spring 5 loaded and a spring-loaded pressure valve D (only depicted schematically). Both valves are pressed into their valve seats and thereby sealed via the forces generated by means of the springs.
  • the compressor chamber R and/or the cylinder wall 1 are at least partially surrounded by a liquid chamber F, which is formed by the liquid medium that is to be compressed.
  • a gas volume and/or gas chamber G is embodied above this liquid chamber F.
  • the openings 2 and 3 depicted in the FIGURE do not show compressor designs that are included in the state of the art.
  • the suction stroke in the process, the compressor piston K moves from the lower to the upper end position
  • liquid medium flows via the suction valve S from the liquid chamber F into the compressor chamber R, whereby, as already explained, the liquid medium at least partially vaporizes.
  • At least two openings 2 and 3 are henceforth provided.
  • one of the openings 2 corresponds to the liquid chamber, while a gaseous medium can be extracted from the compressor chamber R via the other opening 3 .
  • this extraction of the gaseous medium from the compressor chamber R is accomplished via a gas extraction line 4 .
  • the gas generated by the suction process via opening 2 can now exit the compressor chamber R via the opening 3 and be replaced by the liquid medium flowing in after it. This results in an increase in the conveying capacity and a reduction in the specific compression work.
  • the gas compressed by means of the piston K exits the compressor chamber R when pressure valve D is opened via the gas extraction line 6 and is then fed via a high-pressure line to a consumer.
  • the two openings 2 and 3 are embodied in accordance with an advantageous embodiment of the inventive compressor preferably in the form of one and/or more slots.
  • the openings 2 and 3 are preferably located at points on the cylinder wall 1 , which are not passed by the compressor piston K until the compressor piston is directly in front of its upper end position or has arrived at its upper end position.
  • the FIGURE depicts the compressor piston K in its upper end position.
  • the two openings 2 and 3 are henceforth released so that the liquid medium that is to be compressed can flow via the opening 2 from the liquid chamber F into the compressor chamber R (shown by the two parallel arrows).
  • This inflowing liquid medium supplements the liquid quantity F′ already located in the compressor chamber R, which results from the liquid medium flowing in during the suction stroke via the suction valve S.
  • the gaseous medium G′ formed during the suction stroke can escape from the compressor chamber R via opening 3 and/or the gas extraction line 4 . This escape of the gaseous medium is supported by the liquid medium flowing in via opening 2 since the gaseous medium G′ located in the compressor chamber R is displaced from the compressor chamber R by the inflowing liquid medium.
  • the suction valve S has at least one indentation on its surface facing the compressor piston K; the indentation is embodied in this case such that a vacuum forms between the suction valve S and the compressor piston K.
  • the shape of the indentation(s) to be provided on the surface of the suction valve S facing the compressor piston K can be selected at will; crucial is ultimately only that a vacuum be formed between suction valve S and the compressor piston K.
  • one or even several indentations can be provided.
  • the invention described in the foregoing makes it possible to achieve an increase in the amount of liquid in the compressor chamber, which results in a greater conveying capacity of the inventive compressor. Therefore, it is possible to achieve a reduction in the specific compressor output based on the quantity of medium compressed and/or conveyed.
