    • An ultrasonic fluid pressure generator for generating high pressure head in a fluid. The ultrasonic fluid pressure generator comprises a transducer comprising a piezoelectric actuator and a displacement amplifier, the displacement amplifier having a fluid channel therethrough, the displacement amplifier being connected to the piezoelectric actuator at one end and having a free vibrating tip at another end; a reflecting condenser disposed at the vibrating tip of the displacement amplifier to form a gap between the vibrating tip and a reflecting surface of the reflecting condenser; and a casing configured for establishing a standing wave in the fluid contained within the casing, the transducer and the reflecting condenser being at least in part within the casing.
    • 一种用于在流体中产生高压头的超声波流体压力发生器。 所述超声波流体压力发生器包括一个包括压电致动器和位移放大器的换能器,所述位移放大器具有通过其的流体通道,所述位移放大器在一端连接到所述压电致动器并且在另一端具有自由振动尖端; 反射冷凝器,设置在所述位移放大器的振动末端,以在所述振动尖端和所述反射冷凝器的反射表面之间形成间隙; 以及壳体,其构造成用于在容纳在壳体内的流体中建立驻波,所述换能器和反射冷凝器至少部分地在壳体内。
