Abstract
Abstract A regulator device which will selectively regulate about one of two pressure levels is disclosed. The regulator device includes a regulator poppet which defines two pressure sensing areas and a solenoid actuated valve for controlling application of the regulated pressure to either one or both sensing areas to selectively establish, in cooperation with a biasing spring, balanced positions of the poppet commensurate with the two pressure levels. The poppet is disposed in a valve housing and cooperates therewith to modulate the flow from a pressurized fluid source to the region wherein the pressure level is to be regulated.
