摘要： Microfluidic oscillator circuits and pumps for microfluidic devices are provided. The microfluidic pump may include a plurality of fluid valves and a microfluidic oscillator circuit having an oscillation frequency. The fluid valves may be configured to move fluids. Each fluid valve may be connected to a node of the microfluidic oscillator circuit. The pumps may be driven by the oscillator circuits such that fluid movement is accomplished entirely by circuits on a microfluidic chip, without the need for off-chip controls.

摘要： A fluororubber tube is provided, which is formed from a rubber composition containing a fluororubber, and not less than 3.8 parts by mass and not greater than 4.1 parts by mass of a polyol crosslinking agent and not less than 3 parts by mass and not greater than 7 parts by mass of a carbon black based on 100 parts by mass of the fluororubber. Thus, the fluororubber tube is made less tacky by suppressing the intrinsic adhesiveness of the crosslinked fluororubber without formation of a coating film which may otherwise complicate the structure of the tube and the production process of the tube or may result in contamination.

摘要： In one example, a displacement pump has a suction side including a suction check valve, and a discharge side including a discharge check valve. The discharge side and suction side are each configured for selective fluid communication with each other, and the suction check valve defines a flow area that is relatively larger than a flow area defined by the discharge check valve.

摘要： A drainage device for draining liquid out of a closed chamber includes an air cylinder, a driving assembly, a first channel, a second channel, a first sealing assembly, a second sealing assembly, and a controller. The air cylinder includes a main body defining a receiving chamber, an action piston positioned in the receiving chamber of the main body, and a connecting rod connected to the action piston. The main body defines a liquid inlet and a liquid outlet, both of which communicate with the receiving chamber, and the presence of a fixed piston with a seal in each of the inlet and outlet creates a double-acting one-way valve when the action piston is moved up and down.

摘要： An air motor for a pump assembly including a drop tube communicating between an upper chamber port and a top plate port and including a longitudinal axis that is at an angle of between about 0° and 10° with respect to each of the upper chamber longitudinal axis and the top plate port longitudinal axis. The drop tube has a substantially constant internal diameter, a first generally bulbous end, a second generally bulbous end, and first and second slots defined in the respective first and second bulbous ends. First and second seals are positioned in the respective first and second slots, and the first and second seals air-tightly seal an outer surface of the drop tube within the upper chamber port and the top plate port.

摘要： A device for choking a fluid flow includes a pot-like base body, in the base of which a first passage opening is arranged, and a closing body guided axially moveably in the pot-like base body against a spring force of a spring element and having a second passage opening that forms a static choke point with a predefined fixed opening cross section. The closing body in combination with the spring element and the first passage opening forms a dynamic choke point with a dynamic opening cross section that is variably adjustable depending on a pressure difference.
