摘要： A variable-pressure air pump includes a first cylinder with a first chamber and a second cylinder with a second chamber movably connected with one another. The second chamber fluidly communicable with the outside of the variable-pressure air pump selectively. A discharge device includes a connecting member and a switch movably connected with one another. The connecting member defines at least one discharge hole fluidly connecting with the second chamber. The switch has at least one flow guide portion and at least one blocking portion. The switch is movable between a first position in which the at least one flow guide portion is adjacent and opens to the at least one discharge hole and a second position in which the at least one blocking portion is adjacent to and blocks the at least one discharge hole.

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： The present invention discloses a fast inflating air pump, including a housing, an inflating tube, an inlet tube, a motor, a transmission assembly and a controller housed in the housing. A blower is arranged in the inlet tube for increasing air pressure to the inflating port. A piston is at least partially contained in the inflating tube, and the piston is driven by the motor via the transmission assembly so as to slide back and forth linearly for increasing air pressure in the inflating tube. A one-way valve is installed in the communicating pipe for only allowing air flow into the inflating tube. The controller instructs the motor to drive the piston to slide back and forth in the inflation tube on condition that the blower stops working until the air inflation pressure increases to a predetermined threshold, then the controller instructs the motor to stop operating.

摘要： The present invention is directed to a dual engine-compressor system having a crankcase enclosing a crankshaft and having engine cylinder housings and compressor cylinder housings linearly disposed on opposite sides of the crankcase. Combustion pistons are reciprocatingly disposed in the engine cylinder housings and defines alternating combustion chambers on opposite sides of the pistons. Compressor pistons are reciprocatingly disposed in the compressor housings and define alternating low and high pressure compressor chambers on opposite sides of the compressor pistons. The compressor pistons undergo a 4-cycle process to drawn in, re-distribute, and then compress fluid. The compressor cylinder and piston has a series of one-way intakes and reed valves to selectively draw or push fluid in response to movement of the compressor piston.

摘要： A cam driven compressor includes a cam coupled to a plurality of cylinder and piston assemblies. Each cylinder and piston assembly comprises a piston located and movable within a respective cylinder. Each cylinder has a cylinder head. The compressor comprises a housing defining a cavity configured to receive a portion of a source gas from one or more of the cylinders in order to maintain a positive gas pressure within the cavity.

摘要： A method for operating a pressure control system having a multi-stage compressor includes providing a multiply compressed pressure medium by the multi-stage compressor for filling a pressure medium reservoir or pressure medium chambers of the pressure control system. Providing the multiply compressed pressure medium includes (i) providing, by a first compression stage, a pre-compressed pressure medium and additionally compressing, at least by a second compression stage, the pre-compressed pressure medium, and/or (ii) introducing an already-compressed charging pressure medium into an intermediate volume between the first compression stage and the second compression stage of the multi-stage compressor and further compressing the charging pressure medium at least by the second compression stage. The charging pressure medium simultaneously passes via a control line to a control input of a shut-off valve that interacts with the first compression stage, such that a charging pressure of the charging pressure medium predefines a control pressure.
