Embodiment Construction

[0010] The drawing shows a pressure vessel for a gas internal combustion engine according to the invention.

[0011] A pressure vessel 1 for a gas internal combustion engine has an electromechanical fuel tank valve 2 for closing the pressure vessel with two connections 3 , 4 . One connection 3 is fluidically connected to an internal combustion engine 6 , for example via a pressure regulator 5 . The other connection 4 is fluidically connected to a tank filling connection 10 or to another pressure vessel, wherein the pressure vessel 1 can be filled via the fuel tank filling connection 10 . The electromechanical tank valve 2 controls at least one inlet 11 , 12 into the pressure vessel 1 via a valve component (not shown). Arranged at one of the inlets 11 is an air supply line 15 protruding into the pressure vessel 1 , which prevents oil from reaching the fuel tank valve 2 through the inlets 11 , 12 and thus into the internal combustion engine 6 when cornering. This can lead to m...

Abstract

Pressurized reservoirs are known, comprising a tank valve for controlling the filling or empty process and comprising a gas removal pipe disposed on the tank valve. Many gas stations are equipped with oil-lubricated compressors, which provide the necessary pressure for filling the natural gas, but pollute the natural gas with oil. As a result, an increasing amount of oil collects at the bottom of the pressurized reservoirs in the tanks of the vehicles. The gas removal pipe projects into the pressurized reservoir. In the pressurized reservoir according to the invention, oil separation on the gas removal pipe is improved. According to the invention, an oil separation means (16) is provided on the circumference of the gas removal pipe (15).

Description

technical field [0001] The invention relates to a pressure vessel of the kind according to the independent claim. Background technique [0002] From US 2007 / 0246122 A1 a pressure vessel is known which has a fuel tank valve for controlled filling or emptying and an air intake line mounted on the fuel tank valve. Many gas stations are equipped with oil-lubricated air compressors to provide the pressure necessary to charge the gas, but the gas is contaminated with oil. Thus, in the vehicle fuel tank, more and more oil collects at the bottom of the pressure vessel. Take the air pipe and extend into the pressure vessel. Contents of the invention [0003] Advantages of the invention [0004] In contrast, the pressure vessel according to the invention with the features of the characterizing part of the independent claim has the advantage that oil is reliably and simply blocked by the arrangement of the oil separator on the periphery of the gas intake tube. Optionally, no addi...
