Dual high pressure rotary union for mechanical power press

A mechanical press, comprising:

• a frame structure with a crown and bed;
• a slide guided by said frame structure for reciprocating movement in opposed relation to said bed;
• a drive mechanism associated with said frame structure;
• a flywheel assembly rotatably driven by said drive mechanism, said flywheel assembly including a flywheel rotatable relative to said frame structure;
• a shaft rotatably disposed within said crown and in driving connection with said slide, said shaft including two or more fluid pathways formed therein;
• a clutch assembly for selectively connecting said flywheel to said shaft for driving rotation thereof;
• and
• a fluid delivery system for providing fluid to said two or more fluid pathways formed in said shaft, said fluid delivery system comprising:
• a rotary union, disposed for driving rotation by said shaft, in fluid communication with said two or more fluid pathways formed in said shaft;
• a housing means for defining a clearance space with at least part of said rotary union and for providing two or more fluid pathways disposed in fluid communication with said clearance space, said clearance space being disposed in fluid communication with said rotary union;
• and
• sealing means for sealably securing said clearance space.

• and
• a fluid delivery system for providing fluid to said two or more fluid pathways formed in said shaft, said fluid delivery system comprising:
• a fluid transfer means having two or more inlets, adapted for non-rotation and disposed at least in part within a cavity of said shaft to define a clearance space there between, for transferring fluid received at said two or more inlets to said clearance space and to said two or more fluid pathways formed in said shaft;
• and
• a sealing means for sealably securing said clearance space defined between said shaft cavity and said fluid transfer means.
