Abstract
Abstract A solenoid valve useable as a pilot for actuating a flow control valve of the pressure responsive type, the solenoid valve having a coacting valve ball and seat and means upstream of and reciprocable axially of the valve seat for actuating the valve ball which includes a portion for holding said valve ball engaged with the valve seat, a portion spaced from the seated ball for unseating said ball and a valve cage portion in spaced surrounding relation to said valve ball. The valve ball actuating means has at least a portion of magnetic material adapted to function as an armature for a solenoid so as to be attracted thereby for unseating the valve ball, the solenoid including an electromagnetic coil having multifilar windings of fine gauge wire of the order of 0.004 of an inch whereby the coil is of reduced volume and increased efficiency and said solenoid is relatively minute.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
155 words
A solenoid valve including: means forming a housing having an inlet and outlet, means forming an orifice establishing communication between the inlet and outlet and having a valve seat facing upstream and surrounding the orifice, a globular valve member engageable with the valve seat, means for actuating the valve member including a plunger upstream of and reciprocable axially of said orifice and engageable with said valve member for holding said member in engagement with said valve seat, means for biasing said plunger in a downstream direction relative to said valve seat, means extending from said plunger in spaced relationship to said valve member to provide a cage therefor, a nipple extending into and spaced from the cage means and carrying said valve seat, said plunger having at least a portion of magnetic material so as to function as a solenoid armature, and a solenoid for attracting said plunger to permit unseating of said valve member.
Claim 2
Dependent Claim
155 words
A solenoid valve including: means forming a housing having an inlet and outlet, means forming an orifice establishing communication between the inlet and outlet and having a valve seat facing upstream and surrounding the orifice, a globular valve member engageable with the valve seat, means for actuating the valve member including a plunger upstream of and reciprocable axially of said orifice and engageable with said valve member for holding said member in engagement with said valve seat, means for biasing said plunger in a downstream direction relative to said valve seat, means extending from said plunger in spaced relationship to said valve member to provide a cage therefor, a nipple extending into and spaced from the cage means and carrying said valve seat, said plunger having at least a portion of magnetic material so as to function as a solenoid armature, and a solenoid for attracting said plunger to permit unseating of said valve member.
Claim 3
Dependent Claim
30 words
A solenoid valve as defined in claim 1 wherein: the biasing means is in the form of a helical spring surrounding the cage means of the valve member actuating means.
Claim 4
Dependent Claim
73 words
A solenoid valve as defined in claim 1 wherein the means for actuating the globular valve member includes: means movable with the plunger of the valve member actuating means for unseating said valve member upon upstream movement of said plunger relative to the orifice, the means for unseating said valve member being spaced therefrom in its seated position to permit movement of said plunger away from said valve member prior to unseating thereof.
Claim 5
Dependent Claim
30 words
A solenoid valve as defined in claim 3 wherein: the biasing means is in the form of a helical spring surrounding the cage means of the valve member actuating means.
Claim 6
Dependent Claim
153 words
A solenoid valve including: means forming a housing having an inlet and outlet, means forming an orifice establishing communication between the inlet and outlet and having a valve seat facing upstream and surrounding the orifice, a globular valve member engageable with the valve seat, means for actuating the valve member including a plunger upstream and reciprocable axially of said orifice and engageable with said valve member for holding said member in engagement with said valve seat, means for biasing said plunger in a downstream direction relative to said valve seat, a nipple downstream of said plunger carrying said valve seat, means surrounding the nipple and movable with said plunger for unseating said valve member upon relative upstream movement of said plunger, said plunger having at least a portion of magnetic material so as to function as a solenoid armature, and a solenoid for attracting said plunger to permit unseating of said valve member.
