1. A piezo-electric vibrator pump comprising;
- at least one piezo-electric vibrator mounted in a casing having a peripheral part secured to a portion of said casing, a suction non-return valve through which fluid is sucked from a suction line and a discharge non-return valve through which the fluid is discharged from a discharge line by means of a piezo-electric vibrator vibrated by applying an alternative current voltage between electrodes of said piezo-electric vibrator, said suction and discharge non-return valves both being in said casing wall and on the same side of said piezo-electric vibrator;
said piezo-electric vibrator pump having both sides of the piezo-electric vibrator coated with elastic elastomer layers of approximately 0.8 to 10 mm thickness;
said elastic elastomer layers having a modulus of longitudinal elasticity of less than about 5×
108 dynes/cm2.

Abstract
A pump is comprised of a piezo-electric vibrator mounted in a casing. The piezo-electric vibrator is coated with an elastic elastomer layer, and a peripheral part of the elastomer layer is secured to the casing within the casing. Suction and discharge of fluid is performed by means of piezo-electric vibrator vibrated by applying alternative current voltages between electrodes of the piezo-electric vibrator. The vibration of the piezo-electric vibrator is performed smoothly to produce and high discharge volume and discharge pressure can be produced.
