Title: Pneumatic controller
Inventor: GALEAZZI CARLOS J
IPC: F16K31/126
Filed: 2018-09-06
Abstract: A pneumatic controller for connecting to a vacuum source and providing a vacuum output signal. The pneumatic controller includes a valve body defining a number of different chambers. At least two of the chambers that are separated by diaphragm and one of these chambers is maintained at vacuum pressure. In response to a pressure differential between the two chambers, the diaphragm deforms causing a valve to move from a first position, where an output port is coupled to atmospheric pressure, to a second position, where the output port is coupled to vacuum pressure. The valve is inhibited for moving between the first and second positions unless a sufficient vacuum pressure is present.  Movement of the valve from the second position to the first position is also delayed until the two chambers are substantially equalized.
