Abstract:
The Recreational Vehicle Exhaust Fan I have invented makes camping more enjoyable and safer. It removes 100% waste odors and harmful gasses. I have never seen anything like it in use or for sale anywhere. Before my fan, campers just had to suffer with the problem.
Abstract:
A proportioning system includes a cutoff valve, a three-way valve, a check valve and an eductor. The cutoff valve has a cutoff intake port and a cutoff discharge port. The cutoff valve is capable of receiving a carrier fluid from a carrier fluid source and selectively discharging the carrier fluid or inhibiting carrier fluid flow. The three-way valve is capable of receiving a first active fluid and a second active fluid and is capable of selectively discharging a selected one of the first active fluid and the second active fluid, or inhibiting flow from of both the first active fluid and the second active fluid. The eductor is capable of receiving an active fluid when the carrier fluid is passing through the eductor so as to mix the active fluid with the carrier fluid.
Abstract:
A chemical sprayer system includes a three-way valve that includes an inlet port coupled to a fluid source, a first outlet port in fluid communication with a first elongated fluid passage, a second outlet port in fluid communication with a second elongated fluid passage, and a control. The control allows a user to place the three-way valve into one of a first ON state in which the first outlet port is in fluid communication with the inlet port, a second ON state in which the second outlet port is in fluid communication with the inlet port, and an OFF state in which substantially no fluid is allowed to exit the inlet port. The first elongated fluid passage terminates in a nozzle adapted for spraying foam. The second elongated fluid passage terminates in a nozzle adapted for spraying liquids.
