4.1 PRINCIPLE OF OPERATION

Gas is drawn into the pump through

a common inlet, channeled to the

three piston slides and into the

space behind the pistons as they

rotate. The gas ahead of the pistons

is compressed and forced out the

discharge valves. As the gas is

forced through the pump, sealing

oil is mixed with the discharged

gas and the discharged mixture

is channeled into the separator,

which is located in the reservoir,

and there the gas is separated from

the oil. Sealing and lubricating oil

is provided by the oil pump which

is mounted on the non-drive head

and driven by direct coupling to

the vacuum pump drive shaft. The

oil pump provides forced feed oil

circulation at all operating pressures

including atmosphere.

All models have a channeled drive

shaft with an opening at each cam

to distribute oil through the pump.

Oil is taken from the reservoir at

a point some distance above the

reservoir bottom. This provides

an area for impurities to collect for

draining.
