Abstract
Abstract The present invention relates to a washing table with a liquid or water outlet apparatus having a supply line with an electrically operated valve, such as a solenoid valve, controlled by a relay having a control circuit. The circuit includes a pressure-sensitive switch means operated through a fluidcontaining control tube line, a pressure-applying trigger means and a diaphragm to permit facile control of the valve.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
86 words
A liquid outlet apparatus comprising a supply line, an outlet line communicating with said supply line, a valve between said supply and outlet lines including electrical switch means for opening and closing said valve, means for controlling said electrical switch means including a pressure wave switch communicating through a fluid conduit with a pressure trigger means, and a relay means actuated by said pressure wave switch for controlling said electrical switch means, said relay means remaining in said actuated state after said pressure wave has subsided.
Claim 2
Dependent Claim
86 words
A liquid outlet apparatus comprising a supply line, an outlet line communicating with said supply line, a valve between said supply and outlet lines including electrical switch means for opening and closing said valve, means for controlling said electrical switch means including a pressure wave switch communicating through a fluid conduit with a pressure trigger means, and a relay means actuated by said pressure wave switch for controlling said electrical switch means, said relay means remaining in said actuated state after said pressure wave has subsided.
Claim 3
Dependent Claim
73 words
The apparatus of claim 1 having a plurality of supply lines, a valve between each supply line and said outlet line, switch means for independently operating each valve, and means for independently controlling each of said electrical switch means, each control means including a pressure switch communicating through a fluid conduit with a pressure trigger means, and an electrical relay means activated by said pressure wave switch for controlling said electrical switch means.
Claim 4
Dependent Claim
35 words
The apparatus according to claim 2, wherein said pressure wave switches comprise an electrical contact means, and a diaphragm positioned adjacent said contact means, said associated fluid conduit having one end communicating with said diaphragm.
Claim 5
Dependent Claim
13 words
The apparatus of claim 3 wherein said relay means is a bistable relay.
Claim 6
Dependent Claim
32 words
The apparatus according to claim 4 further comprising a nozzle assembly which includes pressure trigger means for applying pressure to move said diaphragm and mixer means for mixing a plurality of fluids.
Claim 7
Dependent Claim
30 words
The apparatus of claim 4 in which each of a plurality of supply lines discharges into a mixer means and in which the outlet line communicates with said mixer means.
Claim 8
Dependent Claim
34 words
The apparatus of claim 6 in which the mixer means is located at the discharge end of said outlet line, said mixer means having control means for controlling the operation of said mixer means.
Claim 9
Dependent Claim
32 words
The apparatus of claim 4 in which at least a portion of said fluid conduit for transmitting pressure to the diaphragm is arranged with said outlet line in a common jacket tube.
Claim 10
Dependent Claim
23 words

Claim 11
Dependent Claim
13 words
The apparatus of claim 3 wherein said relay means comprises a timed relay.
Claim 12
Dependent Claim
32 words
The apparatus according to claim 10 further comprising a nozzle assembly which includes pressure trigger means for applying pressure to move said diaphragm and mixer means for mixing a plurality of fluids.
Claim 13
Dependent Claim
30 words
The apparatus of claim 10 in which each of a plurality of supply lines discharges into a mixer means and in which the outlet line communicates with said mixer means.
Claim 14
Dependent Claim
34 words
The apparatus of claim 12 in which the mixer means is located at the discharge end of said outlet line, said mixer means having control means for controlling the operation of said mixer means.
Claim 15
Dependent Claim
32 words
The apparatus of claim 10 in which at least a portion of said fluid conduit for transmitting pressure to the diaphragm is arranged with said outlet line in a common jacket tube.
Claim 16
Dependent Claim
23 words
The apparatus according to claim 10 having in addition said fluid conduit and said outlet line cast in synthetic resin in a housing.
