    摘要： Rotary pumps wherein the conveyed fluid, e.g. foodstuffs, entering around the rotor seats, is prevented from staying there statically, by circulating part of the fluid from the high-pressure side of the pump chamber to the low-pressure side through appropriate holes or apertures disposed around the rotor seats, and by making use of the fluid pressure itself. Washing can be carried out around the seats by circulating water that is fed to the pump, instead of the fluid, after the use of the pump has been stopped. The pumps feature a fluid circulating passage between the high-pressure side and a space in a cap portion, for purposes of cleaning that space.

    摘要： A rotary compressor having mating rotary impellers defined by lobes and well spaces therebetween, a discharge port sealed by the peripheral surface of one of the lobes and passages for communicating one impeller well space with a well space of the other impeller as the discharge port is sealed by the one impeller peripheral surface. According to one form, the passages are defined by conduits in the compressor housing; whereas according to a second form the passages are defined by a recess in one impeller and the interior of the compressor housing.

    摘要： A gear pump for dispersing a gas into a liquid is provided with mixing means for improving the uniformity of the dispersion. In preferred form, the mixing means comprises a series of fixed, shallow, blind cavities that open to the pumping cavity between the liquid inlet and the outlet, and which are positioned to be "wiped" by the gear teeth as the gears rotate. The alternate connection and disconnection of the intertooth spaces to these cavities as the gears rotate establishes motion or turbulence of the gas/liquid mixture within the intertooth spaces, and surprisingly improves uniformity of the dispersion.
