Claim 3
Dependent Claim
37 words
The combination of claim 1 and wherein said connecting duct means also has operatively connected therewith a valve means for normally permitting flow only in a direction from said intermediate container means toward said output container means.
Claim 4
Dependent Claim
63 words
The combination of claim 1 and wherein a safety duct means communicates with an upper portion of said intermediate container means and an upper portion of said supply tank means and carries a safety valve means for providing for flow of gas from said intermediate container means toward said supply tank means when an excessive pressure is present in said intermediate container means.
Claim 5
Dependent Claim
40 words
The combination of claim 1 and wherein said connecting duct means carries a safety valve means for providing for flow from said output container means toward said intermediate container means when an excessive pressure exists in said output container means.
Claim 6
Dependent Claim
28 words
The combination of claim 4 and wherein said safety valve means is situated at a region of said connecting duct means which is adjacent said intermediate container means.
Claim 7
Dependent Claim
36 words
The combination of claim 4 and wherein said electromagnetic valve means operatively connected with said connecting duct means responds to excessive pressure in said output container means for automatically opening when said excessive pressure is present.
Claim 8
Dependent Claim
66 words
The combination of claim 1 and wherein each of said control means includes a float and an over-center means operated thereby, said over-center means in said intermediate container means controlling said electromagnetic valve means which is operatively connected with said supply duct means while said over-center means in said output container means controls said electromagnetic valve means which is operatively connected with said connecting duct means.
Claim 9
Dependent Claim
28 words
The combination of claim 7 and wherein each of said over-center means includes a magnetic element moved between a pair of positions for controlling the electromagnetic valve means.
Claim 10
Dependent Claim
63 words
The combination of claim 1 and wherein said connecting duct means has a filter means in its interior as well as a spring means acting on said filter means for yieldably maintaining the latter in a position from which said filter means is adapted to yield in opposition to said spring means when an excessive pressure is present in said output container means.
Claim 11
Dependent Claim
172 words
The combination of claim 1 and wherein said connecting duct means carries, for normally preventing reverse flow from said output container means back to said intermediate container means, a valve seat in said connecting duct means, a piston normally engaging said valve seat and a spring urging said piston into engagement with said valve seat, said spring urging said piston in the direction of flow from said intermediate container means to said output container means against said valve seat, and said piston being formed with a bore passing therethrough and containing a check valve means for permitting flow through said bore of said piston only from said intermediate container means toward said output container means, said piston having an exterior surface formed with axial grooves so that when an excess of pressure occurs in said output container means the excess of pressure will act on said piston to displace the latter away from said seat permitting flow through said grooves at the exterior of said piston back toward said intermediate container means.
