ABSTRACT:
The automatic hydraulic valve control apparatus is intended for use in combination with a lavatory waste tank of a vehicle, such as an airplane. The waste tank includes a drain, a rinsing valve, and a fluid pressure charging inlet. The hydraulic valve control apparatus includes a drain control valve biased to be in an open position, a drain valve responsive to opening of the drain control valve and fluid pressure in line, a rinse valve control including a timing circuit to control the amount of pre-charging of the tank once the drain closes, and a drain control valve actuator including a timing circuit operating to close the drain after a desired period of time. An anti-siphon circuit is also provided to allow a given amount of gas to enter the charging line once rinsing and pre-charging of the waste tank are completed.
