A gas supply system for a mechanical seal turns on the gas supply at a pressurized flow rate at the time of compressor case pressurization and remains on during compressor rotation until pressure is adequate. The gas supply system has an intensifier that includes a pair of mechanically inter-connected pneumatic pressure cylinders which comprise a drive cylinder that affects movement of a boost cylinder wherein the displacement of these mechanically interconnected pistons in the drive cylinder and boost cylinder intensifies the pressure being discharged b...
1. An intensifier for a mechanical seal gas supply system comprising: a drive cylinder which is operatively connected to a boost cylinder by an intermediate piston rod, said drive cylinder having a pressurized cylinder housing which defines a drive pressure chamber subdivided into variable-volume, first and second cylinder chambers by a reciprocating drive piston;said boost cylinder having a pressurized cylinder housing which defines a boost pressure chamber that is subdivided into variable-volume, third and fourth cylinder chambers by a reciprocating bo...
