A/C System Components
This valve prevents damaging the through-vanes or the reed valve (which
should “see” only refrigerant gas) by allowing liquid oil to escape from the
c
ompression area into an oil chamber.
Some Toyota vehicles use a swash-plate (also called “wobble plate”) type
compressor. Some models use multiple, opposed pistons arranged around
a single swash-plate with two compression chambers for each cylinder.
The cylinders connect to reed valves and common inlet and outlet passages
at each end. The swash-plate converts the rotary motion of the shaft into
smooth back and forth motions of the pistons. This design provides
reduced vibration and allows more pulses per revolution than a two-piston
reciprocating compressor.
