Pump module for printing machine

A continuous inkjet printer includes an ink circuit. A first part of the ink circuit includes hydraulic components for providing a print head of the CIJ printer with ink and solvent. A second part of the ink circuit includes a first single-block assembly including at least part of at least a first pump and a second single-block assembly including at least one filter. Each of the assemblies further includes: a housing having at least one fluid inlet and at least one fluid outlet; fluid connections to allow fluids to flow from the at least one fluid inlet, to the at least part of a first pump or said filter and then to the at least one fluid outlet; and a structure for mounting and disassembling the first single-block assembly and the second single-block assembly to and from the first part of the ink circuit, independently from each other.

Ink circuit with several modular units

This delivery module includes: a pump for making the liquid flow; and an electronic circuit for controlling the pump. The delivery module further includes a channeling block having two channeling elements which define, when they are superimposed, channels for the liquid and which include: an inlet channel and an outlet channel.

Liquid delivery module, a method for assembling such a delivery module and a tank set comprising such a delivery module

A heating device intended to heat body, such as fluid contained in fluid circuit, the device including at least one electric heating element, as well as at least one control module to electrically power the heating element, the heating element being formed by propulsive winding circuit of direct-current electric motor which, when it is electrically powered by a direct supply voltage, generates drive force which tends to drive the motor in direction of displacement determined by the polarity of the supply voltage, and the control module including activation mode called heating oscillating mode, according to which the control module causes a warm-up of the propulsive winding circuit by Joule effect by applying at the terminals of the winding circuit an alternating supply voltage whose polarity switches, alternately and automatically, according to predetermined frequency called heating frequency, from a first polarity to opposite second polarity.

This transfer device includes at least one body defining at least partially a transfer conduit having a first orifice and a second orifice, and one heating member arranged at least partially in the body so as to heat the at least one transfer conduit. The first orifice and the second orifice are offset i) on the one hand, along a first direction, and ii) on the other hand, along a second direction, the second direction being perpendicular to the first direction.

Liquid transfer device and a tank assembly comprising such a transfer device

A lightweight gear pump easy to manufacture, having a reduced manufacturing cost, while giving sufficient performances. It consists of: A gear, three metal plates, placed on each other, an intermediate plate of which including an eight-shaped cavity adapted to house the gear, and two peripheral plates having the function of enclosing the gear in the cavity, a circuit for fluid supply to the gear, centering means to align the three plates above each other, the three metal plates being provided with centering holes in the axial direction, adapted to receive the centering means, the device according to the invention is particularly intended for liquid transfer applications for automobiles or heavy trucks.

Plate gear pump and hydraulic centering pins

The invention concerns a circuit intended to transfer, by means of a pump, first fluid, such as an aqueous urea solution, from a reservoir to an injector, said circuit also containing a second fluid, such as air, and said circuit comprising, downstream of the pump and of the reservoir, a downstream circuit portion which includes, on the one hand, a main branch which leads to the injector and, on the other hand, bypass branch which returns to the reservoir and which is provided with a double-seat valve designed to selectively and automatically adopt: purge configuration allowing to purge the second fluid through the valve out of the main branch, a pressurized supply configuration allowing to direct the first fluid to the injector under a predetermined working pressure, and a recirculation configuration allowing a recirculation through the bypass branch, and to the reservoir, of the first fluid coming from said reservoir.

Urea depollution circuit comprising a double-seat valve selectively ensuring the degassing or the recirculation of the aqueous urea solution

This valve includes a first chamber, a second chamber, a seat with a liquid passage, a plug movable between i) an open position and ii) a closed position, and a biasing member for urging the plug toward the closed position. The valve includes an actuating member having a face which sustains an actuating pressure. The actuating member is movable between i) an actuation position for opening the plug and ii) a rest position. The valve operates, selectively: in a feed mode, where the plug is open and the actuating member is at rest, the liquid flowing in one direction throughout the second chamber, or in a latch mode, where the plug is closed and the actuating member is at rest, no liquid flowing in the valve, or in a drain mode, where the plug is open, the liquid flowing in the reverse direction throughout the second chamber.
