The original Accusump™ oil accumulator |
The original Accusump oil accumulator was patented
in 1978 (#4,094,293) after years of research and camparison between different
designs. At that time and since then we have tried and tested many ways of
applying accumulator technology to automotive applications and found our design
to be superior to all others.

Bottle style accumulator |
- Some of the other accumulators that are on the market use a bottle design.
This design has many shortcomings.
- Because of the lack of a bladder or a piston seperating the air
against the oil, they can become mixed through typical automotive vibrations
and movements allowing air to escape into the engine. As the air escapes into
the engine the unit becomes less and less effective.
-
The bottle design must be mounted vertically to effectively hold
and discharge any measurable amount of oil.
- Vertical mounting is a major installation problem in most
applications because of the amount of available room.
- Without a means to seperate the air and oil the unit cannot be
precharged with air. This lack of a precharge makes the operating pressure
range very low.
- Many units use a smaller connections which cannot provide enough
of a flow needed for surge control.
- While the bottle design is available in the manual and electric
versions we have found them to be less than effective.

Electric motor driven pre-oiler |
- Some of the other accumulators that are on the market use an electric motor driven design.
This design also has many shortcomings.
- This design is overcomplicated which means more parts to fail and
more maintenance.
- Some of these designs draw unfiltered oil straight from the
bottom of the pan, usually through the drainplug to use for pre-oil.
- These units are only designed for pre-oiling and do not
provide surge protection.
- In comparison, our design is simple and provides more by
it's pre-oiling and surge protection capabilities.

Accusump imitations |
- Our original design has been upgraded over the years to provide
the most reliable unit on the market.
- We use screw in end caps with safety clamps to prevent failure.
- Our unit comes with a safety high pressure blow-off valve.
- Heavy wall aluminum tubing.
- Double o-ring sealed piston.
- Air pressure gauge.
- Schrader type air precharge valve.
