Abstract
Abstract An electromagnetic valve for a sorting machine has a chamber in which there is a valve disc. The valve disc is urged to an open position by the energisation of a solenoid and in the open position pressure fluid may leave the chamber through an exit. In the closed position a portion of the edge of the valve disc prevents flow of pressure fluid from the chamber. The valve disc may be replaced by a tubular member.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
179 words
An apparatus for controlling the flow of a pressure fluid, the apparatus comprising: a chamber; means defining an inlet through which pressure fluid may be supplied to the chamber; means defining an outlet through which pressure fluid may exit from the chamber; a valve disc having an edge region disposed within the chamber; means for mounting the valve disc at a position adjacent a first portion of the edge region whereby the valve disc is capable of pivotal movement between a first position and a second position, the valve disc being urged towards the first position; a solenoid device which, when energized, causes the valve disc to move to the second position; and a second portion of the edge region, substantially opposite to the first portion of the edge region, the second portion of the edge region in one of the positions of the valve disc preventing flow of the pressure fluid from the chamber to the outlet and in the other position of the valve disc permitting flow of the pressure fluid from the chamber to the outlet.
Claim 2
Independent Claim
179 words
An apparatus for controlling the flow of a pressure fluid, the apparatus comprising: a chamber; means defining an inlet through which pressure fluid may be supplied to the chamber; means defining an outlet through which pressure fluid may exit from the chamber; a valve disc having an edge region disposed within the chamber; means for mounting the valve disc at a position adjacent a first portion of the edge region whereby the valve disc is capable of pivotal movement between a first position and a second position, the valve disc being urged towards the first position; a solenoid device which, when energized, causes the valve disc to move to the second position; and a second portion of the edge region, substantially opposite to the first portion of the edge region, the second portion of the edge region in one of the positions of the valve disc preventing flow of the pressure fluid from the chamber to the outlet and in the other position of the valve disc permitting flow of the pressure fluid from the chamber to the outlet.
Claim 3
Dependent Claim
39 words
An apparatus as claimed in claim 1 in which the valve disc is so shaped that when it is in the said other position it is in a stressed condition which urges the valve disc towards said one position.
Claim 4
Dependent Claim
29 words
An apparatus as claimed in claim 1 in which the said inlet is so positioned as to cause pressure fluid to urge the valve disc towards said one position.
Claim 5
Dependent Claim
34 words
An apparatus as claimed in claim 1 in which the valve disc is annular, so that in the second position pressure fluid may flow from the inlet to the outlet through the valve disc.
Claim 6
Dependent Claim
26 words
An apparatus as claimed in claim 1 in which the said other position is the second position, the valve disc being urged towards the first position.
Claim 7
Dependent Claim
40 words
An apparatus as claimed in claim 1 including means for adjusting the position of the said second portion of the edge region of the valve disc relative to the outlet when the valve disc is in the said one position.
Claim 8
Dependent Claim
37 words
An apparatus as claimed in claim 1 in which the outlet is in the form of a convergent-divergent nozzle having an inlet end for receiving pressure fluid from the chamber, a throat portion and an outlet end.
Claim 9
Dependent Claim
28 words
An apparatus as claimed in claim 7 in which said nozzle is so dimensioned as to provide a supersonic flow of gaseous pressure fluid at the outlet end.
