Claim 1
Independent Claim
278 words
A public drinking water fountain including a fluid supply valve for pressurized water which comprises: a cylindrically shaped fluid chamber having first and second ends, a peripheral wall and an interior portion, said first end having formed therein a cylindrical fluid inlet passage and said peripheral wall having formed therein a fluid outlet passage; a cylindrical housing having first and second ends and an interior portion, said first end being flanged and said second end being located adjacent said second end of said fluid chamber; means for governing the flow of water through said fluid chamber comprising a spring wound elongated actuation member which defines a recess at one end; an elastic disk-like seal which engages the flange of said cylindrical housing and which is configured to define a central integral cylindrical projection on its exterior face, said seal being operative to prevent flow of water from said cylindrical housing to said actuation member; and a cylindrical plug-like body having first and second ends, and being adapted to slidably fit the inlet passage of the fluid chamber, said plug-like body traversing the interior of the fluid chamber and the interior of the cylindrical housing such that first end of the plug-like body rests against the interior face of the disk-like seal, said recess in said actuation member being operative for engaging the central integral projection of the disk-like seal, whereby displacement of the actuation member is transmitted to the disk-like seal, which transmits the displacement to the plug like body thereby causing it to slide in a transverse fashion in the fluid chamber thereby allowing fluid to flow through the chamber and out through the fluid outlet passage.

A public drinking water fountain including a fluid supply valve for pressurized water which comprises: a cylindrically shaped fluid chamber having first and second ends, a peripheral wall and an interior portion, said first end having formed therein a cylindrical fluid inlet passage and said peripheral wall having formed therein a fluid outlet passage; a cylindrical housing having first and second ends and an interior portion, said first end being flanged and said second end being located adjacent said second end of said fluid chamber; means for governing the flow of water through said fluid chamber comprising a spring wound elongated actuation member which defines a recess at one end; an elastic disk-like seal which engages the flange of said cylindrical housing and which is configured to define a central integral cylindrical projection on its exterior face, said seal being operative to prevent flow of water from said cylindrical housing to said actuation member; and a cylindrical plug-like body having first and second ends, and being adapted to slidably fit the inlet passage of the fluid chamber, said plug-like body traversing the interior of the fluid chamber and the interior of the cylindrical housing such that first end of the plug-like body rests against the interior face of the disk-like seal, said recess in said actuation member being operative for engaging the central integral projection of the disk-like seal, whereby displacement of the actuation member is transmitted to the disk-like seal, which transmits the displacement to the plug like body thereby causing it to slide in a transverse fashion in the fluid chamber thereby allowing fluid to flow through the chamber and out through the fluid outlet passage.
Claim 3
Dependent Claim
75 words
A water fountain according to claim 1 and also comprising: a screw thread at the first end of the plug-like body; a retaining nut having first and second ends, said retaining nut attached to said screw thread; and a spring would about the plug-like body, said spring located adjacent first end of the retaining nut and thereby biasing the plug-like body to remain adjacent the disk-like seal regardless of the pressure of the fluid supply.
Claim 4
Dependent Claim
33 words
A water fountain according to 1 and also comprising a fluid regulator for supplying water at a substantially constant pressure to the valve regardless of the variation of the pressure at the source.
Claim 5
Dependent Claim
33 words
A water fountain according to 1 and also comprising a fluid regulator for supplying water at a substantially constant pressure to the valve regardless of the variation of the pressure at the source.
