Abstract
Abstract A compact valve block for an I.S. glassware forming machine comprises two rows of valve combinations each of which comprises a pilot-operated poppet valve under the control of a solenoidoperated pilot valve which directs pilot air to the poppet valve, and a plenum chamber, preferably an exhaust chamber, which is located adjacent to all the valve combinations and which is common to either all the supply ports or, preferably, all the exhaust ports of all the poppet valves.

Claim 1
Independent Claim
202 words
A valve block for an I. S. glassware forming machine comprising a plurality of valve combinations arranged in two rows, each valve combination comprising a pilot-operated poppet valve having a supply port, an outlet port and an exhaust port and a solenoid-operated pilot valve for directing pilot air to the poppet valve, a pilot line in the valve block common to the pilot valves on all the valve combinations, a first plenum chamber located adjacent all the valve combinations and in fluid communication with the exhaust ports of all said poppet valves, said first plenum chamber being sufficiently large relative to each exhaust port such that the opening of one of said exhaust ports of one of said poppet valves to admit exhaust air to said first plenum chamber does not result in a large fluctuation in the pressure of the air in the exhaust chamber, and a pair of supply plenum chambers each mounted adjacent a respective one of the rows of valve combinations and separated from said first plenum chamber by the associated row of valve combinations, each supply chamber being in fluid communication with the supply ports of the poppet valves of the valve combinations in its associated row.

A valve block for an I. S. glassware forming machine comprising a plurality of valve combinations arranged in two rows, each valve combination comprising a pilot-operated poppet valve having a supply port, an outlet port and an exhaust port and a solenoid-operated pilot valve for directing pilot air to the poppet valve, a pilot line in the valve block common to the pilot valves on all the valve combinations, a first plenum chamber located adjacent all the valve combinations and in fluid communication with the exhaust ports of all said poppet valves, said first plenum chamber being sufficiently large relative to each exhaust port such that the opening of one of said exhaust ports of one of said poppet valves to admit exhaust air to said first plenum chamber does not result in a large fluctuation in the pressure of the air in the exhaust chamber, and a pair of supply plenum chambers each mounted adjacent a respective one of the rows of valve combinations and separated from said first plenum chamber by the associated row of valve combinations, each supply chamber being in fluid communication with the supply ports of the poppet valves of the valve combinations in its associated row.
Claim 3
Dependent Claim
66 words
A valve block as defined in claim 1, wherein the two rows of valve combinations are located in a segment of the block which extends parallel to one face of the block, the valve combinations in the two rows extending in opposite directions from a center line along said segment, and said first plenum chamber is located in an adjacent and parallel segment of the block.
Claim 4
Dependent Claim
22 words
A valve block as defined in claim 1, wherein said first plenum chamber is disposed between said two rows of valve combinations.
Claim 5
Dependent Claim
34 words
A valve block as defined in claim 3, additionally comprising an outlet manifold in fluid communication with the outlet ports of all the poppet valves and disposed between the two rows of valve combinations.
Claim 6
Dependent Claim
245 words
A valve block for an I. S. glassware forming machine comprising a plurality of pneumatic valve combinations each extending laterally across the valve block and arranged in two rows which extend longitudinally along the valve block and are separated vertically from each other, each combination comprising a pOppet valve having a supply port, an outlet port and an exhaust port and a solenoid-operated pilot valve for directing pilot air to the poppet valve, a pilot line in the valve block common to the pilot valves of all the valve combinations, a supply plenum chamber disposed between the two rows of valve combinations and common to the supply ports of all the poppet valves, said supply plenum chamber being sufficiently large relative to each supply port such that the opening of one of said supply ports of one of said poppet valves to supply air to said poppet valve does not result in a large fluctuation in the pressure of the air in the supply plenum chamber, an outlet manifold located adjacent the supply chamber between the two rows of valve combinations and communicating with the outlet ports of all the poppet valves, and a pair of exhaust chambers, each mounted adjacent a respective one of the rows of valve combinations and separated from the supply chamber by the associated row of valve combinations, each exhaust chamber being in communication with the exhaust ports of the poppet valves of the valve combinations in its associated row.
