The present invention relates to a fluid conduit system and manufacture thereof, for the propulsion of fluids. The micro- or millifluidic system is useful within LOC, POC diagnostics digital ELISA, drug delivery applications or sampling. The system includes a capillary pump and a fluid conduit operationally connected to the pump, and a gas-permeable liquid-sealed unit with a vent hole gas-permeable to the outside. The fluid conduit includes a first conduit zone prefilled or pre-Tillable with a first volume of trigger liquid, upstream of the unit with the vent hole, a third conduit zone with a further volume, upstream of the capillary pump, and a second conduit zone pre-filled or pre-Tillable with a working liquid between the first and third conduit zones, connected to both, and directly connected to the first conduit zone. The first volume is proportionally larger than or equal to the volume of the third conduit zone.

A fluid pump for pumping fluids using actuators, like loudspeakers or piezoelectric elements that are arranged in a fluid chamber side by side to each other to generate a fluid flow by driving the actuators with phase shifted signals, so that fluid is sucked into an inlet end of the fluid chamber and pushed out of an outlet end of the fluid chamber.

An electrically-driven compressor is installed in an engine. Refrigerant is compressed with rotation of a rotating shaft in a compression unit. An electric motor is coupled to the rotating shaft and drives the compression unit through the rotating shaft. A housing accommodates the compression unit, the electric motor, and the motor drive circuit aligned in the listed order in the axial direction of the rotating shaft. The housing is internally provided with the discharge chamber through which the refrigerant compressed by the compression unit is discharged. The weight is attached to the housing and disposed in the discharge chamber in a manner that a resonance frequency of the electrically-driven compressor is shifted relative to a resonance frequency of the engine, the weight including a material having a specific gravity greater than a specific gravity of a constituent material of the housing.

A dispensing pump for liquids, viscous materials, foams, gels, etc. includes a resilient plastic skirt spring so that the entire pump can be more easily recycled. The skirt spring comprises a plurality of concentric nesting rings sequentially decreasing in diameter from a base ring to a top ring to form a conical shape wherein adjacent rings are interconnected by spaced bridge segments and the bridge segments are staggered at each sequential ring.

A fluid transportation device comprises a valve main body, a valve chamber base, a valve membrane, an actuator and a cover body. The valve main body comprises an inlet passage and an outlet passage. The valve chamber base comprises an inlet valve passage, an outlet valve passage and a compressible chamber communicating therewith. The valve membrane is arranged between the valve main body and the valve chamber base, having two valve plates respectively form a valve switch structure which seal the inlet valve passage and the outlet valve passage. The actuator covers the compressible chamber. The cover body covers the actuator and has a plurality of screw holes, which are corresponding to the penetration holes of the valve main body, the valve chamber base and the actuator, and several locking elements are inserting the penetration holes and locked with the screw holes to assemble the fluid transportation device.
