Abstract
An intermittent fluid delivery system includes a fill tank and a batch tank which is connected to the fill tank via a first pump and a first hose. The fill tank holds a first quantity of fluid. The batch tank holds a second quantity of fluid, which is lesser than the first quantity. The first pump delivers fluid from the fill tank to the batch tank. A second pump delivers fluid from the batch tank to a receiving tank.
Claims5
An aircraft lavatory filling system, comprising:
- a fill tank sized to hold a first quantity of fluid;
- a batch tank coupled to the fill tank via a first pump and a first hose, wherein the batch tank is sized to hold a second quantity of fluid that is less than the first quantity of fluid and that is intermittently delivered from the batch tank to an aircraft lavatory system;
- a second pump and a second hose for delivering the second quantity of fluid from the batch tank to the aircraft lavatory system;
- a power switch to activate the first pump when the power switch is being held in a first position, and to activate the second pump when the power switch is being held in a second position;
- and
- wherein the batch tank includes an overfill hose for draining back to the fill tank any fluid overfilling the batch tank.
