  • Overflow check system
    Patent number: 4623301
    Abstract: An overflow check system 10 blocks overflow from a vapor powered, liquid pressure amplifier 11 except when required during start-up. Amplified output pressure derived from amplifier 11 enables a check valve 27 to close the overflow during operating intervals, and this pressure is trapped at the end of an operating interval to keep check valve 27 enabled and the overflow closed during inoperative intervals. Absence of amplified output pressure, which occurs when a delivery valve 17 opens on demand, overrides or disables check valve 27, opening the overflow line 20 and allowing amplifier 11 to start-up.
