The device comprises a chamber (1) provided with an inlet (2) and an outlet (3); a piston (4) inside the chamber (1), the movement of which causes the exit of the substance; and a motor (5) with an output shaft (6) that drives the motion of said piston (4) when it receives a signal from a sensor; and transmission means that transmit the drive movement from the motor (5) to said piston (4); characterised in that said transmission means comprise: a worm gear (7) rotationally attached to the output shaft (6) of the motor (5); a first transmission element (8) connected to said piston (4); and a second transmission element (9) connected to said worm gear (7) and to said first transmission element (8). The device enables small dimensions compared to conventional devices.

A valvular conduit, preferably a Tesla valvular conduit, in which a plug member is coaxially received within a bore in a sleeve member and in which passageways are defined between the plug member and the sleeve member within interior walls configured to permit mixing of fluid flowing through the passageways in at least one direction, preferably, the relatively free passage of fluid through the passageways upstream but increased the resistance to downstream flow of the fluid through each passageway.

A flow divider for diverging a fluid includes a main body that includes first and second side surfaces being opposite to each other along a central axis of the main body. The first side surface has a central segment transversely intersecting the central axis, and having an inlet channel recessed toward the second side surface, a generally annular channel surrounding the central segment, recessed toward the second side surface, and spatially communicated with the inlet channel at a junction space, and an inclined segment surrounding the annular channel. A width of the annular channel decreases gradually from a start measurement to an end measurement along a rotational direction with respect to the central axis.

The invention provides a fluid pump apparatus comprising a fluid inlet, a fluid outlet, a screw member and a rotatable pump member. The screw member has at least one helical screw blade configured to be rotated by a fluid flow stream and the rotatable pump member is in fluid communication with the fluid inlet and/or fluid outlet.

The present relates to a Metal hydride compressor control method for generating a variable output pressure P.sub._desired_outPut, comprising a first step of inflowing gaseous hydrogen into a metal hydride compartment at a constant temperature and then stopping the gaseous hydrogen inflow, a second step of heating the metal hydride to a predetermined temperature which corresponds to a temperature which passes through the α+β phase at the desired output pressure P.sub._desired_output, a third step of opening the output connection of the compressor and keeping it at a constant pressure by regulating the temperature to keep a constant output pressure P.sub._desired_outPut until the system completely leaves the α+β phase.

The present invention relates to vacuum pump, to the extent that the difficulties of putting similar products in automatic assembly and production and the technical issues of carrying out one-piece plastic production, assembly and recycling would be resolved. A pump core assembly, the pump body of the pump core assembly is provided with an elastic sleeve, the inner diameter of the upper plug of the first inner plug outwardly of the pump body is provided with a lower elastic cavity that is larger than the inner diameter of the plug, the inner diameter hole of the upper plug of the first inner plug is provided with the upper elastic cavity of the outer diameter of the first valve stem whose outer diameter is smaller than the inner diameter of the upper plug. The spring is substituted by the first plastic spring, the said first valve stem is substituted by the second valve stem, or the said large ring is substituted by an inner ring, an outer guard and a rotating ring, the spring is substituted by the second plastic spring.
