Definitions
- the invention relates to a compressor, in particular compressors for cryogenic media, preferably for liquid hydrogen, comprising a cylinder wall surrounded by a compressor chamber in which a compressor piston is moved linearly, a suction valve and a pressure valve, wherein both valves arranged in the region of the lower end position of the compressor piston are.
- cryogenic media are to be understood below as cryogenic liquids, in particular liquid hydrogen, liquefied natural gas, liquid nitrogen, liquid oxygen and other liquefied gases.
- Compressors of any kind are well known in the art. They all have in common that passed through a spring-loaded suction valve, the medium to be compressed in a compressor room, compressed and then withdrawn via a spring-loaded pressure valve from the compressor room.
- FIG. 1 shows in a laterally schematic sectional illustration a generic compressor construction belonging to the prior art.
- a compressor piston K is moved linearly back and forth or up and down within a compressor chamber R surrounded by a cylinder wall Z.
- the two reversal points of the compressor piston K ' are referred to below as the lower and upper end position of the compressor piston K'.
- a suction valve S and a pressure valve D 1 are arranged on the underside of the cylinder chamber.
- About the suction valve S occurs during the suction cycle - while the compressor piston K 1 moves from its lower end into its upper end position, in the present case from bottom to top - the liquid medium to be compressed in the compressor chamber R.
- the compressor piston K 1 moves from its upper again to its lower end position, which is shown in the figure 1 - the compressed medium via the pressure valve D 'from the compressor chamber R is pushed or ejected , Especially during the liquid compression of a liquid cryogenic medium, a gas phase G inevitably occurs during compaction.
- Cylinder space Z to lead and thus reduce the dead space or "eliminate". This is due to the fact that the dead space of compressors is optimized. Due to the length expansions during cooling, a certain dead space can not be prevented. If no dead space was provided, the valves could not be integrated into the compressor.
- Object of the present invention is to provide a generic compressor, in particular a generic compressor for cryogenic media, specify, in which the aforementioned disadvantages can be avoided.
- a generic compressor is proposed, which is characterized in that the pressure valve in the region of the lower end position of the compressor piston is arranged laterally on the cylinder wall and the head of the compressor piston has a conical shape.
- Figure 2 shows - as already the figure 1 - a lateral schematic sectional view through a possible embodiment of the compressor according to the invention.
- the compressor piston K is now in its lower end position at the end of the pressure or compression cycle - as shown in FIG. 2 - the remaining dead space G filled with gaseous medium is now substantially smaller than that shown in FIG compressor design. Furthermore, because of the conical shape x of the compressor piston K, there is or is a "connection" to the pressure valve D, so that the compressed cryogenic medium can be expelled from the dead space via the pressure valve D.
- compressor according to the invention it is achieved that the gas content in the compressor chamber at the end of the pressure or compression cycle is completely eliminated or at least largely reduced; this results in a higher capacity compared to known compressor designs.
- a reduction of the specific compressor capacity relative to the amount of the conveyed or compressed medium can be achieved.
