Method and apparatus for purging air from automatic lubrication systems

摘要: An automatic lubrication system where grease is dispensed to injectors from a pump having piston (42) reciprocated by connecting rod an oil (43) driven alternating hydraulic pressure, provided with air purge valves (41) associated each injector. The detect abnormal operation of the movement due in way indicators (45) and (46) communicating chambers pump, open valve dump laden into recovery reservoir (48).
