Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
236 words
A two-tank liquid-vacuum generator for use with a two chamber cleaning nozzle comprising: a housing, vacuum means, mounted within the housing, and having an intake and an outlet, a liquid pump, mounted within the housing, and having an intake and an outlet a vacuum tank mounted on the housing, a standpipe extending upwardly from the bottom of the vacuum tank, a vacuum line communicating the intake side of the vacuum means with the lower end of the standpipe, a vacuum inlet extending inwardly through the side of the vacuum tank below the top of the standpipe and downwardly inside the tank, a solution tank mounted on the housing, a solution supply line extending from the bottom of the solution tank to the intake side of the liquid pump, and a liquid tube having one end thereof communicating with the pump and the other end thereof formed for releasable connection to the cleaning nozzle, characterized in that: The solution tank is located inside the vacuum tank and has an open top above the level at which the vacuum inlet pipe enters the vacuum tank, but below the top of the standpipe, and further characterized in that a solution inlet pipe extends inwardly through an upper portion of the vacuum tank and opens into the top of the solution tank, the inlet pipe being adapted for releasable connection to a liquid tube leading to a remote solution reservoir.
Claim 2
Dependent Claim
236 words
A two-tank liquid-vacuum generator for use with a two chamber cleaning nozzle comprising: a housing, vacuum means, mounted within the housing, and having an intake and an outlet, a liquid pump, mounted within the housing, and having an intake and an outlet a vacuum tank mounted on the housing, a standpipe extending upwardly from the bottom of the vacuum tank, a vacuum line communicating the intake side of the vacuum means with the lower end of the standpipe, a vacuum inlet extending inwardly through the side of the vacuum tank below the top of the standpipe and downwardly inside the tank, a solution tank mounted on the housing, a solution supply line extending from the bottom of the solution tank to the intake side of the liquid pump, and a liquid tube having one end thereof communicating with the pump and the other end thereof formed for releasable connection to the cleaning nozzle, characterized in that: The solution tank is located inside the vacuum tank and has an open top above the level at which the vacuum inlet pipe enters the vacuum tank, but below the top of the standpipe, and further characterized in that a solution inlet pipe extends inwardly through an upper portion of the vacuum tank and opens into the top of the solution tank, the inlet pipe being adapted for releasable connection to a liquid tube leading to a remote solution reservoir.
Claim 3
Dependent Claim
39 words
The generator of claim 1 in which at least a portion of the top of the vacuum tank is of a transparent material, so as to form a viewing port for the monitoring of solution levels within the tanks.
Claim 4
Dependent Claim
47 words
The geNerator of claim 2 in which the top of the vacuum tank is of a transparent material, and the solution inlet pipe enters the transparent top of the solution tank and extends in a downwardly direction to a point below the top of the solution tank.
Claim 5
Dependent Claim
24 words
The generator of claim 1 in which means are provided for closing the standpipe when the solution level approaches the top of the standpipe.
Claim 6
Dependent Claim
14 words
The generator of claim 4 in which the closing means comprises a float valve.
