    摘要： An air-driven generator system for generating electric power from movement of a working liquid. The system includes an air-driven generator that includes a liquid turbine system fluidically interposed between the lower end of an elongate gravitational distribution conduit and the lower ends of plural elongate buoyancy conduits. A heavy working liquid flows from the upper ends of the buoyancy conduits and is fed into the upper end of the elongate gravitational distribution conduit. Working liquid flows down the elongate gravitational distribution conduit to actuate the liquid turbine system. An injection of air into the working liquid in the plural elongate buoyancy conduits induces upward flow of the working liquid. The system includes a solar thermal heating system fluidically coupled to heat exchangers that transfer heat collected by the solar thermal heating system to the working fluid through a thermal transfer fluid circuit.

    摘要： A compressor includes: a driving unit including a stator, a rotor, and a rotary shaft provided in the rotor, having an oil guide path formed at an inner side in a radius direction; a compression unit coupled to the rotary shaft, having a cylinder and a piston reciprocating in the cylinder by a driving force of the driving unit; and an oil supply unit coupled to a lower end of the rotary shaft, supplying oil toward the compression unit. The oil supply unit includes a rotary portion for supplying oil toward the oil guide path while being rotated together with the rotary shaft and a fixed portion having an inner space partitioned to accommodate at least a portion of the rotary portion, and the oil guide path is formed to pass through the rotary shaft along a length direction.

    摘要： An oscillating positive displacement pump with at least one mobile part arranged to be movable relative to a fixed part. The mobile part is driven and drives a displacement element of the positive displacement pump. An electrodynamic drive is provided as a drive, on which a plurality of coils and permanent magnets are provided that are arranged on the mobile part of the drive respectively, and at least one guide member is provided on the drive, which allows the mobile part to move only along a degree of translation freedom. The positive displacement pump is designed as a diaphragm pump, which is associated with a measurement and control unit with a data storage and data processor, which processes a position signal of the mobile part and the strength of the drive current as a measured and/or control variable. An arrangement of a plurality of such positive displacement pumps and a method of operating at least one such oscillating positive displacement pump are also provided.

    摘要： A system comprises: a vacuum chamber disposed within a housing and having a vacuum port; a vacuum pump within the housing and having a gas inlet port that is fluidically coupled to the vacuum port; and a fluid circuit that comprises: one or more fluidic tubing lines, channels or conduits in thermal contact with a housing of the vacuum pump; a liquid pump fluidically coupled to an inlet of the one or more fluidic tubing lines, channels or conduits; and a heat exchanger having a heat exchanger inlet and a heat exchanger outlet, wherein the heat exchanger inlet is fluidically coupled to an outlet of the one or more fluidic tubing lines, channels or conduits and the heat exchanger outlet is fluidically coupled to the liquid pump. The fluid circuit may also include a portion that is in thermal contact with the vacuum chamber.
