Abstract
Abstract A valve assembly for selectively directing air to either a point of use, such as a nozzle, or to a vent passage, which includes a valve body having a central passage having a restricted portion, a splitter for dividing the passage into two portions and a valve member operatively associated with the splitter and extending into the restricted portion for selectively directing air into either of the two portions of the central passages. The valve member comprises a magnetizable U-shaped resilient valve member having one leg portion fixed to tee valve body and a free leg portion extending into the restricted portion. The apparatus additionally includes an electromagnetic coil or winding disposed about the valve member and the valve body which, when energized, actuates the free leg portion to move it from its normally open nonactuated to its actuated position. The valve assembly may also include a magnetic strip also magnetizable by the current flowing in the winding which cooperates with the free leg portion to increase its speed and efficiency of operation. A combination of a plurality of the above described valve assemblies are disposed in a plenum of a housing into which air is introduced under pressure, each of the valve assemblies selectively directing air to either a vent passage or to nozzles mounted on the housing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
180 words
A valve assembly including: a valve body having a main bore therethrough, said main bore having a restricted portion; divider means in said body dividing said main bore downstream of said restricted portion into a first passage and a second passage; and a resilient and substantially U-shaped valve member having first and second substantially parallel legs and a bight portion connecting said legs, said first leg having an end portion remote from said bight portion fixedly secured to said valve body and said second leg being free to move resiliently toward and away from said first leg, said second leg having a free end portion remote from said bight portion extending into said restricted portion of said main bore, said free end portion being movable between a first position and a second position and cooperating with said divider means for selectively directing fluid flowing into said restricted portion into one of said passages when said free end portion is in said first position and into the other of said passages when said free end portion is in said second position.
Claim 2
Dependent Claim
180 words
A valve assembly including: a valve body having a main bore therethrough, said main bore having a restricted portion; divider means in said body dividing said main bore downstream of said restricted portion into a first passage and a second passage; and a resilient and substantially U-shaped valve member having first and second substantially parallel legs and a bight portion connecting said legs, said first leg having an end portion remote from said bight portion fixedly secured to said valve body and said second leg being free to move resiliently toward and away from said first leg, said second leg having a free end portion remote from said bight portion extending into said restricted portion of said main bore, said free end portion being movable between a first position and a second position and cooperating with said divider means for selectively directing fluid flowing into said restricted portion into one of said passages when said free end portion is in said first position and into the other of said passages when said free end portion is in said second position.
Claim 3
Dependent Claim
81 words
The valve assembly of claim 1, said valve member being of a magnetic substance, and a winding disposed about said valve member which when energized by electric current causes the end portions of said legs remote from said bight portion to be of like magnetic polarities whereby said free end portion is moved away from said fixed end portion of said first leg and from one of said first and second positions to the other of said first and second positions.
Claim 4
Dependent Claim
20 words
The valve assembly of claim 2, wherein said winding is of substantially cylindrical configuration and substantially surrounds said valve member.
Claim 5
Dependent Claim
19 words
The valve assembly of claim 2, and an auxiliary magnetic strip having an end portion in said restricted portion.
Claim 6
Dependent Claim
70 words
The valve assembly of claim 4, wherein said end portion of said magnetic strip extends substantially parallel to and in alignment with said free end portion, said magnetic strip extending from said restricted portion away from said bight portion whereby said end portion of said magnetic strip in said restricted portion is magnetized to be of the opposite magnetic polarity than said free end portion when said winding is energized.
Claim 7
Dependent Claim
20 words
The valve assembly of claim 5, wherein said winding is of substantially cylindrical configuration and substantially surrounds said valve member.
Claim 8
Dependent Claim
68 words
The valve assembly of claim 1, wherein said valve member is of magnetic substance, and means for magnetically polarizing said fixed and free end portions of said first and second legs to cause said free end portion to be moved away from said fixed end portion and from one of said first and second position to the other when said end portion of said legs are magnetically polarized.
Claim 9
Dependent Claim
75 words
The valve assembly of claim 7 and an auxiliary magnetic strip having an end portion in said restricted portion extending substantially parallel to and in alignment with the free end portion, said magnetic strip extending from said restricted portion away from said bight portion whereby said end portion of said magnetic strip in said restricted portion is magnetized to be of the opposite magnetic polarity than said free end portion when said winding is energized.
