Abstract
An apparatus for venting and/or degassing a pipeline system includes an upwardly extending casing formed of a top part and a bottom part with a cap located within the casing and extending transversely of the upward direction in the region where the top part is connected to the bottom part. A valve is located in the upper end of the top part and has a horizontally extending valve needle projecting into the interior of the casing. A float needle is located within the top part of the casing and is in interengaged contact with the valve needle. A float is freely slidable on the float needle between the cap and the upper end of the casing. The top part of the casing and the float needle are dimensioned so that the float can move upwardly and downwardly on the float needle from the region of the cap toward the valve needle so that during a pressure increase within the casing up to a predetermined value there will be an accurate safety dimension maintained between the liquid surface in the casing and the valve. To prevent damage to or contamination of the valve, it is provided with a labyrinth outlet port.
