Engine driven vacuum pump |
| abstract |
ENGINE DRIVEN VACUUM PUMP Abstract of the Disclosure An engine driven vacuum pump combining a two-stage, low noise demountable pump assembly with a camshaft driven eccentric drive arrangement having internal oil distribution and pumping means for lubricating the drive and pump pushrod elements. A check valve in the cover of the pump assembly defines a second stage pumping chamber which increases pump efficiency while at the same time cyclically closing the pump outlet to reduce external noise attributable to gas dis-charge from the primary pumping chamber. |
