Abstract: The occurrence of fluctuations in liquid chemical during the discharge and intake thereof in a device that employs a liquid chemical supply pump 10 that discharges liquid chemical taken in by means of a change in volume inside a pump chamber 16 that accompanies the displacement of a bellows type partition 14. The amount of fluctuation in the bellows type partition member 14 that accompanies the operation of a discharge side valve 32 will be detected by a displacement sensor 58. The amount of fluctuation is a parameter that indicates a correlation with the abrupt flow of liquid chemical that accompanies the opening of the discharge side valve 32. Thus, the amount of fluctuation will be reduced, and the pressure inside a pump chamber 16 prior to the opening of the discharge side valve 32 will be controlled.

Abstract: In an effective method for starting a piston compressor which is easy to implement, and a piston compressor suitable for carrying out the method, there is provision, in a resetting phase, for driving a piston of the piston compressor in the direction of a compression point of the piston position by the application of a resetting drive moment. The resetting drive moment being maintained until the piston has reached a starting position by overstepping a steady-state point as a result of displacement of fluid out of the compression space, formed between the piston and a corresponding pressure cylinder, through at least one leakage point. In a subsequent acceleration phase, the piston is then accelerated out of the starting position into an operational direction of rotation with a starting drive moment.

Abstract: A drive circuit (18) produces a drive signal having a waveform of a predetermined waveform shape for a device (10) having a piezoelectric actuator (14). The drive circuit (14) includes a memory (140) which stores waveform shape data which is utilized by the drive circuit in producing the drive signal. The drive circuit utilizes the waveform shape data so that, for each of plural points comprising a period of the waveform, the drive signal has an appropriate amplitude for the predetermined waveform shape. The waveform shape data has preferably been prepared to optimize one or more operational parameter(s) of the device. Preferably the waveform shape data has been prepared by solving a waveform equation, the waveform equation having coefficients determined to optimize at least one operational parameter of the device. The number of coefficients determined for the waveform equation depends on the number of harmonics of the waveform that are within a bandwidth of the device. Other aspects concerns devices which utilize the drive circuit, methods for operating devices, the memory (212) which is utilized by the drive circuit (e.g., the drive circuit which produces the drive signal for the device having the piezoelectric actuator) to store the waveform shape data, as well as apparatus and method for generating the optimized waveform shape data.

Abstract: A pressure exchanger system having at least two tubular chambers, in which a plurality of reversing valves reverse the flow paths of fluid flows through the at least two tubular chambers. At least one driven reversing valve alternately reverses the flow paths between a supply source, which supplies a high-energy high-pressure fluid, and the tubular chambers. In reversing the liquid flows and shutting off previously open flow paths, the driven reversing element in the reversing valve executes a discontinuous or variable movement sequence.
