Connecting unit having a gas pressure regulating apparatus mounted between a gas cylinder and a gas burner apparatus

A connecting unit having a gas pressure regulating apparatus adapted to be mounted between a gas cylinder containing a fuel gas and a gas burner apparatus for domestic and camping use, which connecting unit includes a first portion adapted to be mounted to the gas cylinder and a second portion adapted to be mounted to the gas burner apparatus,

• wherein the connecting unit comprises a housing with a gas inlet located at the area of the first portion, and a gas outlet located at the area of the second portion;
• which gas pressure regulating apparatus is arranged in said housing and includes a reaction area disk adapted to be acted upon on one side by ambient pressure and at the other side by gas pressure, which reaction area disk is mounted to a spring member;
• which first portion includes snap-action members adapted to establish a connection to the gas cylinder;
• and which second portion includes a flexible hose part mounted in an undetachable manner to said housing and rotatable thereto;
• said reaction area disk consists in a metal or a metal alloy and is integrally mounted to said spring member;
• and wherein the pressure regulating apparatus comprises a pivoting arm designed as a single arm lever, which pivoting arm is pivotably mounted at one end to the housing and is coupled at the opposite end to the reaction area disk;
• which pivoting arm includes a baffle plate adapted to be acted upon by inflowing gas and located between the two ends, which baffle plate is located at a distance from the end of the pivoting arm pivotably mounted to the housing which is multiply smaller than the distance from the end coupled to the reaction area disk.
