Abstract
Abstract By the present invention there is provided a system for connecting a sequentially controlled washing machine to a faucet supplying liquid under line pressure, including a coupling attachable to the faucet and a multipassageway conduit connecting the coupling to the machine. A solenoid controlled water valve is encapsulated in the housing between the line pressure faucet inlet area and an outlet area communicating with a passageway in the conduit for introducing water at flow pressure to the washing machine only when the solenoid controlled water valve is energized. The electrical wires necessary for energizing the solenoid valve at predetermined times in the machine cycle are brought to the solenoid from the machine sequence control system through another passageway in the conduit. Effluent from the washing machine is directed through still another passageway in the conduit and discharged through an appropriate passageway in the housing.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
200 words
A coupling assembly connecting an automatic washing machine having an automatic sequence control means to a line pressure water supply faucet for introducing water to said machine at predetermined times in a cycle of operation of said machine comprising: a body portion defining a water passageway therein having an inlet end removably connected to the faucet and an outlet passageway for transmitting water from said passageway toward said machine and a discharge passageway for receiving fluid from said washing machine; an electrically operable water inlet valve disposed in said passageway for allowing the introduction of water into said machine at predetermined times in a cycle of operation of said automatic machine; a multipassageway conduit connected at one end to said body portion including a first passageway connecting said outlet passageway with said washing machine for introducing water into said machine, a second passageway connecting said washing machine to said discharge passageway for receiving effluent from sAid machine, and a third passageway for receiving wires for electrically connecting said water valve to said automatic washing machine sequence control means for allowing the introduction of water into said machine at predetermined times in a cycle of operation of said automatic washing machine.
