  • Patent number: 11283373
    Abstract: A piezoelectric power apparatus wherein piezoelectric material forms one wall of a liquid-filled container. Water pressure within the container is made to rapidly vary either by a cam operated piston or a motor operated ball valve acting on a pressurized liquid flow. The piston reciprocates through a wall of the container to alternately increase and decrease the pressure in the liquid. The ball valve periodically interrupts the pressurized liquid flow to alternately increase and decrease the pressure in the liquid. In either case, the alternate increase and decrease in the pressure in the liquid creates pressure variations in the piezoelectric material.

  • Patent number: 10168242
    Abstract: A glow plug adaptor for pressure measurement in a combustion chamber of an internal combustion engine includes an adaptor sleeve attached to an adaptor head that contains a pressure sensor with a diaphragm. A sealing shoulder can be screwed into an opening in a combustion chamber to provide a pressure-tight seal and permit passage of signal conductors from the pressure sensor through the adaptor sleeve. The adaptor head is tapered at the proximal combustion chamber end, and in the adaptor head a cavity is formed in such a way that the cavity is bounded by the diaphragm of the pressure sensor mounted therein and by a closed end wall of the adaptor head.

  • Patent number: 10161823
    Abstract: A piezoelectric pressure sensor includes a sensor housing that accommodates a membrane, a piezoelectric sensor, a charge pick-off and a pre-stressing assembly. The membrane captures a pressure profile, and polarization charges are generated accordingly on the piezoelectric sensor by the captured pressure profile. The pre-stressing assembly includes a pre-stressing body and a pre-stressing sleeve and mechanically pre-stresses the piezoelectric sensor. The charge pick-off receives the polarization charges and is electrically insulated from the pre-stressing sleeve by a second gap. The charge pick-off is mechanically connected to the pre-stressing body via a first electric insulation body on a side of the pre-stressing body that faces away from the membrane and seals the second gap in a pressure-tight manner from an environment of the second gap.

  • Patent number: 10119874
    Abstract: A pressure transducer comprising a flexible member made of amorphous quartz and a crystalline quartz sensor are coupled together without an adhesive material. Instead, the amorphous quartz and the crystalline quartz sensor are coupled together at the molecular level. In some embodiments, the crystalline quartz sensor remains in compression or tension during the entire operating range of the pressure transducer. In one embodiment, the crystalline quartz sensor is pre-stressed in either compression or tension when the pressure transducer is exposed to atmospheric pressure. In one embodiment, pressure transducer is located in pressure stabilizing system.
