Title: Variable capacity wobble plate compressor
Inventor: KUROSAWA JUETSU
IPC: F04B27/14
Filed: 1987-01-13
Granted: 1989-11-30
Abstract: The compressor has a wobble plate swung axially as the drive shaft rotates.  Pistons are connected to the wobble plate to make reciprocating motions in response to swinging of the wobble plate. A change in the angularity of the wobble plate causes a change in stroke of the reciprocating motions of the pistons so that the capacity of the compressor is varied.  A sensing element arranged on the wobble plate is moved along a predetermined orbital path together with swinging of the wobble plate.  A sensor arranged on an element passes by the sensor as the wobble plate swings.  A control unit determines the rotational speed of the compressor and the angularity of the wobble plate.

The  dye  for  the  first dye-coated film is yellow (CI acid yellow 23, CI acid yellow 36 or CI basic yellow 2) and the dye for the second dye-coated  film  is magenta (CI basic voilet 14, CI basic red 9, CI basic violet 2  or CI solvent red 41), or vice versa.
