LPG pump and method for operating a LPG pump

摘要

The invention relates to a liquid gas pump for compressing liquefied gas, comprising a cylinder head (1), in which an oscillating piston (2) is accommodated, wherein the piston (2) delimits a cylinder space (3) which via an inflow opening (4) with liquid gas can be supplied from a liquefied gas storage. According to the invention, in the region of the inflow opening (4), a gas recirculation line (5) opens into the cylinder space (3), via which the cylinder space (3) at least partly during a filling cycle and / or after a filling cycle of the liquid gas pump with the liquid gas reservoir, preferably with a head region of Flüssiggasspeichers. The invention further relates to a method for operating such a liquid gas pump.
