The innovation - named "SafeTank" - is a dual-compartment liquid tank assembly, consisting of an upper chamber and a lower chamber, that are secured together, in a leak-proof manner. Between the two chambers is a flexible membrane. Each chamber has an inlet port and an outlet port.
The tank assembly is primarily intended for use in towable RV’s (recreational vehicles) - but can be used for marine applications - for holding, but separating, clean (“fresh”) water and dirty (“grey”) water.
The product provides three important benefits to Travel Trailers (Caravans) and Camper-Trailers:
1: It allows the dirty water to be retained in the vehicle, until it can be drained, in a responsible manner.
2: It allows the total mass of the tank, and its contents to remain substantially the same while travelling, thus allowing the coupling-load to remain substantially the same, hence not possibly impairing the handling and stability of the vehicle.
3: It significantly reduces the “sloshing” of the water, thus improving the stability of the vehicle.
Each chamber has an inlet port and an outlet port, which are connected, via suitable fittings, to the appropriate water hoses.
Fig. 1 depicts a tank assembly where the membrane is flat.
Fig. 2 depicts a tank assembly where the membrane is convoluted, and has two rigid supporting plates attached to it.
The drawings illustrate two typical embodiments of the innovation, components of which are designated by:
1: Upper chamber
2: Lower chamber
3: Flexible membrane
4: Inlet port
5: Outlet port
6: Supporting plate
Clean water is delivered into the upper chamber (1) through its inlet port (4).
Clean water is withdrawn from the upper chamber (1) through its outlet port (5).
Dirty water is delivered into the lower chamber (2) through its inlet port (4).
Dirty water is withdrawn from the lower chamber (2) through its outlet port (5).
A single tank assembly would preferably be mounted ahead of - and close to - the axle(s), while any additional tank(s) would be mounted behind - and close to - the axle(s).
Drainage ports, with suitable plugs or taps, may be positioned at the bottom of each chamber, to enable the chambers to be flushed out, using clean water, and completely drained of sediment.
