Piezo-electric compressor with displacement amplifier

A compressor having a piston cylinder assembly for successive suction and discharge of a compressible fluid, thereby increasing fluid pressure of said compressible fluid in a substantially closed chamber, wherein said piston and cylinder assembly comprises a piston, a cylinder, a suction plenum having a suction valve, and a discharge plenum having a discharge valve, said compressor comprising:

• at least one piezoelectric element;
• a primary displacement member coupled to said at least one piezoelectric element;
• a secondary displacement member coupled to said piston;
• and
• a non-compressible fluid disposed to fill a fixed predetermined volume between said primary displacement member and said secondary displacement member;
• wherein, in response to electrical actuation of said at least one piezoelectric element, displacement of said secondary displacement member is amplified relative to displacement of said primary displacement member, said displacements being based upon said fixed predetermined volume and surface areas of said primary displacement member and said secondary displacement member in contact with said non-compressible fluid.

A fluid conveying apparatus having a piston cylinder assembly for successive suction and discharge of a fluid, wherein said piston and cylinder assembly comprises a piston, a cylinder, a suction plenum having a suction valve, and a discharge plenum having a discharge valve, said fluid conveying apparatus comprising:

• at least one piezoelectric element;
• a primary displacement member coupled to said at least one piezoelectric element;
• a secondary displacement member coupled to said piston;
• and
• a non-compressible fluid disposed to fill a fixed predetermined volume between said primary displacement member and said secondary displacement member;
• wherein, in response to electrical actuation of said at least one piezoelectric element, displacement of said secondary displacement member is amplified relative to displacement of said primary displacement member, said displacements being based upon said fixed predetermined volume and surface areas of said primary displacement member and said secondary displacement member in contact with said non-compressible fluid.
