<p>Liquefied petroleum gas is widely used in leisure time activities. Here, as liquefied petroleum gas is highly inflammable, it is important to have an indicator (19) that quickly determines whether there is leakage. The present invention relates to a new leak indicator (19) that, when an easily operated button (20) is pushed downwards into a cavity (8), indicates whether or not there is leakage. The space confined in the cavity (8) is completely closed off when the appertaining liquefied petroleum gas system is in normal operation mode.</p> |
