Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
356 words
A solenoid operated compressed air valve, comprising: a valve housing, within which are located first and second coaxial bores that are spaced apart; each said bore has a respective interior end; a respective pressure passage communicating with each said bore interior end; an inlet passage communicating with both said bore interior ends; in said first bore is positioned a respective first valve holder; in said second bore is positioned a respective second valve holder; each said valve holder has a bottom side facing the respective said bore interior end; each said valve holder having a passage through it communicating with the respective said pressure passage; a valve element in each said bore and supported by the respective said valve holder on the side of said holder that is away from said interior end of that said bore; said holders being shiftable toward and away from their respective said bore ends and said bores being of an axial length sufficient to accommodate such movement of said holders; feet project from each said holder bottom side; the feet on each said holder are located so that and are of a length so that the ends of the respective feet on each said holder may normally abut each other; said feet being of a length and said bores being of a length such that with said holders in said bores, said feet can remain abutting as said holders shift; feet receiving bores which are separate from said pressure passages pass through said housing and extend between said coaxial holder bores; said feet receiving bores are shaped closely to the exterior contour of said feet and said feet can slide therethrough and are guided thereby; apart from said valve housing is an electromagnetically operated solenoid having an armature which is positioned adjacent said first valve holder to engage and activate same by moving toward said first valve holder and shifting it; said abutting feet causing said second valve holder to correspondingly shift; a return spring operatively connected to and applying force to said second valve holder to move said valve holders against the movement caused by activation of said armature.
Claim 2
Dependent Claim
356 words
A solenoid operated compressed air valve, comprising: a valve housing, within which are located first and second coaxial bores that are spaced apart; each said bore has a respective interior end; a respective pressure passage communicating with each said bore interior end; an inlet passage communicating with both said bore interior ends; in said first bore is positioned a respective first valve holder; in said second bore is positioned a respective second valve holder; each said valve holder has a bottom side facing the respective said bore interior end; each said valve holder having a passage through it communicating with the respective said pressure passage; a valve element in each said bore and supported by the respective said valve holder on the side of said holder that is away from said interior end of that said bore; said holders being shiftable toward and away from their respective said bore ends and said bores being of an axial length sufficient to accommodate such movement of said holders; feet project from each said holder bottom side; the feet on each said holder are located so that and are of a length so that the ends of the respective feet on each said holder may normally abut each other; said feet being of a length and said bores being of a length such that with said holders in said bores, said feet can remain abutting as said holders shift; feet receiving bores which are separate from said pressure passages pass through said housing and extend between said coaxial holder bores; said feet receiving bores are shaped closely to the exterior contour of said feet and said feet can slide therethrough and are guided thereby; apart from said valve housing is an electromagnetically operated solenoid having an armature which is positioned adjacent said first valve holder to engage and activate same by moving toward said first valve holder and shifting it; said abutting feet causing said second valve holder to correspondingly shift; a return spring operatively connected to and applying force to said second valve holder to move said valve holders against the movement caused by activation of said armature.
Claim 3
Dependent Claim
155 words
The pressure valve of claim 1, further comprising a first valve seat at the said bore interior end of said first bore and a second valve seat at said bore interior end of said second bore; said valve seats being adapted to cooperatively seal against the respective said valve element when the respective said valve holder is moved toward the respective said bore interior end; said inlet passage and the respective said pressure passage communicates with each said valve seat to be sealed by sealing movement of the respective said valve element; said return spring acting upon said second valve holder to move its respective said valve element to said second valve seat; a valve spring connected with said first valve holder for moving its respective said valve element toward said first valve seat; said return and valve springs acting in opposition and said return spring having a higher spring constant than said valve spring.
Claim 4
Dependent Claim
40 words
The pressure valve of claim 1, wherein said first valve holder includes a cap thereover on the side of its respective said valve element away from its respective said bore interior end which said cap is engaged by said armature.
Claim 5
Dependent Claim
73 words
The pressure valve as claimed in claim 2, wherein an axially adjustable screw plug is inserted into said valve housing at a location to define an end of said first bore which end is opposite said first bore interior end; said valve spring is a compression spring which, on the one hand, presses against said first valve holder and its said valve element and on the other hand presses against said screw plug.
Claim 6
Dependent Claim
24 words
The pressure valve as claimed in claim 2, wherein each said valve seat is conically shaped, tapering narrower toward the respective said valve element.
Claim 7
Dependent Claim
17 words
The structUre as set forth in claim 1, in which said valve holders consist of plastic material.
