Tubeless Face Gland Seal

Resumo

A face gland seal in which the packing is not divided into individual chambers is presented. The packing is pressed by the end face of an axially moveable ring caused by a force created by the pressure of the compacted medium. This force produces a minimal unit axial load that is uniformly distributed along the length of the packing and is specified by the air-tightness condition. The tightening force of the threading elements and losses of power caused by friction of the packing are reduced. Required computational expressions are presented.
