Abstract:

A pressure regulator utilizing a gauge having rugged internal components. In one embodiment, the gauge has a low profile and is mounted to the regulator body. In another embodiment, the gauge is integral with the regulator body. In one preferred embodiment, the gauge includes a pressure pin and a bias, such as a spring. One side of the pressure pin communicates directly with the source pressure and is urged by the source pressure to move the pressure pin in a first direction, while the other side of the pressure pin is at a known pressure, such as ambient or atmospheric pressure, and is urged by the bias to move the pressure pin in a second direction opposed to the first direction. An indication of the position of the pressure pin is sensed by a user and is used to determine the source pressure or level. In one aspect, the indicator is a pointer or indicator mounted to move in response to movement of the pressure pin and mounted so that its position is visible (i. e. , sensed by sight) to the user.
