Abstract

This present invention relates to a piezoelectric pump device with associated valve components, an active and passive fluidic pump chamber capable of pumping liquids, gases and flowable materials. The active pump chamber incorporates a unidirectional inflow means and a unidirectional outflow means. The passive chamber vents to ambient conditions and provides an area for travel of a piezo actuator. The piezoelectric pump mechanism has either a single piezoelectric actuator or a plurality of piezoelectric actuators operating either in phase or out of phase to one another. A power source or power supply provides a voltage or power to the actuator and a regulation means may be adjusted to provide varying amounts of power. Said power supply system is capable of being controlled by a micro-controller or an external computer system the frequency of operational signal voltage can either be of the same frequency or of different frequency. In addition said piezoelectric pump system may also operate at subsonic, sonic, or ultrasonic frequencies, or any combination thereof necessary for a useful function. By supply power to the piezo actuator, the actuator moves on at least three axes and provides an alternating cupped­shaped and planar surface. This alternating action in turn forms a pumping condition. Said piezoelectric pump mechanism also incorporates a power supply system comprising a control means for flow rate and head pressure.

BEST MODE The piezo electric pump 1 , relates to fluid pumps and especially to piezoelectric pumps wherein the resonant operational frequency of the driving element, namely the piezoelectric ceramic material and resonant plate component, are incorporated to form a pump motor system. Said pump motor system along with an inflow and outflow valve system comprises the entire piezoelectric fluid pump embodiment.
Figure 1 shows in an embodiment of the piezo pump which includes: a pump housing which forms a chamber the chamber is divided by a resonant disc which can be the piezo element. A series of seals maintains the resonant disc
The resonant disc moves in three axes so as to approximate a cup shape and planar shape alternately

A microcontroller controls the supply of voltage to the resonating disc
A series of voltages which, correspond to waveforms of different frequencies and wave shapes, are supplied to the resonant disk. The housing, which forms the chamber, may be constructed from Acrylic, Teflon, Polycarbonate, Nylon, Delrin, PVC, ABS, Polyimide, PBI, PEEK, aluminum, stainless steel, titanium, or any other suitable metal per application.
The resonating disc may be constructed from a metallic or non-metallic material. Teflon, Polycarbonate, Nylon, Delrin, PVC, ABS, Polyimide, PBI, PEEK, aluminium, stainless steel, titanium, or any other suitable metal per application.
The power supply may be constructed from a DC to AC inverter to supply AC to the piezoelectric transducer for proper operation of said pump.
The microcontroller may be of type that controls the frequency and voltage; a timer circuit, such as a 7556 CMOS dual timer chip can be utilized to drive said piezoelectric transducer(s).
The series of instructions to the microcontroller are: (1) generate a signal to operate at optimum value, the flow rate of said piezo pump, (2) generate a signal to operate at optimum value, the head pressure of said piezo pump. (3) Monitor the feedback signal from said piezo transducer to determine the maximum vibration amplitude of said piezoelectric transducer.
Dimensions of resonating disk: The dimension of the resonating disk is within a range diameter of 0.5 to 6.5 inches and a thickness, which can vary from 0.001 to 0.025 inches.
Example The dimensions of the housing and chamber will vary, but presently I use a 1.
378-inch resonant disk plate. The dimensions of the chamber are 1.350 inches in diameter by 0.025 inches deep. Another version is 3.2 inches in diameter by 0.053 inches deep. (1) Of the present invention, which can be fabricated from a plurality of materials, and within this pump housing a piezoelectric ceramic disk element (2) mounted on a resonant disk plate (3) and together comprises a piezoelectric transducer (2&3). Said piezoelectric transducer (2&3) is situated parallel to the face plane of said pump housing (1). The piezoelectric transducer (2&3) is laminated and encapsulated respectively with polyimide for strength, and silicon or Teflon for isolation of the transducer element from the fluid being pumped.
Fluid enters the inflow nozzle (9a) and into inflow valve (9) where it enters and fills the pump chamber (7). It is then forced out of said pump chamber, by the push pull action of the resonant vibration of said piezoelectric transducer, and exits through the outflow valve (8) and outflow nozzle (8a). Excitation voltage of proper optimum operating amplitude and proper optimum resonant frequency is applied to wires (6), which are electrically connected by solder joint (5) to said piezoelectric transducer. One electrical connexion applied to the top face plane of said piezoelectric ceramic disk element, and the other electrical connexion applied to the resonant disk plate, which transfers the electric field to the bottom face plane of said piezoelectric ceramic disk element.
The pumping operation defined by the amount of fluid pumped per unit time and the pressure of fluid being pumped per unit time is directly related to the amplitude and frequency of the applied excitation voltage to said piezoelectric transducer.
Figure 2 is an illustration of a dual chamber iezoelectric pump device, showing an embodiment of the piezoelectric pump which includes: a pump housing which forms a chamber the chamber is divided by a resonant disc which can be the piezoelectric element (14). A series of upper and lower chamber seals maintains the resonant disc (17&18) The resonant disc moves in three axes so as to approximate a cup shape and planar shape alternately
The resonant disc divides the housing into a first chamber (19) and a second chamber (20).
First chamber (19), during an upward stroke of said piezoelectric transducer (14), causes a fluid to be forced through outflow valve system (22) and simultaneously in the second pump chamber (20) fluid is being suctioned into said second pump chamber through the inflow valve system (23). During a downward stroke of said piezoelectric transducer (14), said fluid is forced out of said second pump chamber (20) through outflow valve system (24) and simultaneously, fluid is suctioned into said first chamber (19) through inflow valve system (21). This entire procedure of the resonant disc moving in three axes so as to approximate a cup shape and planar shape alternately is repeated over time as a continuous pumping action. Said dual chambered piezoelectric pump can function as a continuous action pump or as a metered pump with pumping action controlled by manual or micro-controller means.
Said dual chambered piezoelectric pump's two individual pump sections can operate separately, connected in series or parallel for a variety of applications.
Figure 3 illustrates a tri chambered pump device of the present invention, defined as having two different piezoelectric transducers (31&31) and with three separate and isolated pump chambers (28,29, &30); in addition each pump chamber has special to itself an in flow and outflow valve system (35,36,37,38,39, &40).

FIGURE 4 is a break away drawing of a quad transducer dual chambered piezoelectric pump device. Four piezoelectric transducers (42), comprised each of a piezoelectric disk element and resonant disk plate, mounted in a 90 degree cubical arrangement along and further this is mounted to a face plate (43) all of said face plates (43) form a cubical container, which is filled with some working fluid such as oil or water or gas and further this container is sealed against any leakage of said working fluid. There exist two pump chambers (44) opposite to each other and separated by the pump cube. They both have inflow valve systems (45) and outflow systems (46). Further the two plates (43), which are mounted behind said pump chambers, contain a flexible membrane. In operation when all four piezoelectric transducers are electrically excited by a signal source, and they are in phase with each other, the summation action of their oscillations, which is an in phase momentum resultant, is transmitted to the flexible membranes. Said flexible membranes oscillate in unison with said four transducers. The oscillating membranes act as the pump motor driving fluid in and out of said pump chambers through said inflow valve (45) and outflow valve (46) systems.

Once voltage is applied, the resonating disc moves forward and back in a cup-shaped configuration within at least three axis of movement. The movement of the disc provides the pumping suction and expulsion.
