Abstract

A pump (100) includes a pump block (102) including a heater (140), a middle block member (120) and an upper block member (122). Cylinder sleeves (130) are disposed between the middle and upper block members, and a piston assembly (160) is disposed in the block with pistons (162) reciprocatingly disposed in the cylinder sleeves. A drive motor (90) drives a twin gear assembly (170) and slave gears (168) to drive the pistons. Headers (104, 105) channel fluid from an external source to the cylinder sleeves, and from the cylinder sleeves to the heater. The heater includes a plurality of heaters such as cartridge heaters (150) that heat the received fluid. In the preferred device, A-side and B-side component are simultaneously pumped. The heater includes A-side and B-side flow paths for heating the components. The pressurized fluid(s) is dispensed through outlets (108, 110).

Dependent claims

A radial pump comprising:

a pump block defining a plurality of radially disposed cylinders;
a plurality of pistons, each piston associated with one of the plurality of radially disposed cylinders;
a plurality of connecting rods, each connecting rod having a first end and a second end, the first end being pivotably connected to one of the plurality of pistons;
a drive assembly rotatably disposed in the block, the drive assembly comprising a central slave gear and a hub assembly pivotably attached to the slave gear such that the hub assembly moves along a circular path as the slave gear rotates, and wherein the connecting rods are attached to the hub assembly such that rotation of the slave gear causes the plurality of pistons to reciprocate within the associated cylinder;
a plurality of headers attached to the pump block, each header associated with one of the plurality of radially disposed cylinders, each header adapted to receive a fluid component and channel the received fluid component to the associated cylinder, further comprising an A-side component inlet that is adapted to be fluidly connected to a source of A-side fluid component, and a B-side component inlet that is adapted to be fluidly connected to a source of B-side fluid component, and further wherein half of the plurality of headers are fluidly connected to the A-side component inlet, and the other half of the plurality of headers are fluidly connected to the B-side component inlet;
and
a heater attached to the pump block, the heater comprising an A-side component flow path and a B-side component flow path, and further comprising a first plurality of heating elements associated with said A-side component flow path, and a second plurality of heating elements associated with said B-side component flow path.

A two-component radial pump for pumping and heating an A-side component and a B-side component, the pump comprising:

a pump block comprising a lower block member defining a heater, a middle block member and an upper block member, the pump block defining a plurality of outwardly disposed faces;
a plurality of cylinder sleeves retained by the middle block member and the upper block member, the cylinder sleeves defining an opening at one of the plurality of outwardly disposed faces;
a piston assembly rotatably disposed in the pump block, the piston assembly comprising a plurality of pistons, wherein each piston is adapted to reciprocate within one of the plurality of cylinder sleeves;
a means for rotatably driving the piston assembly;
a plurality of headers, each header attachable to one of the plurality of outwardly disposed faces defined by the pump block, each header comprising an inlet port and an outlet port, and wherein each header defines an inlet flow path between the inlet port and the opening defined by one of the cylinder sleeves, and an outlet flow path between the cylinder sleeve and the heater;
wherein some of the plurality of headers are adapted to receive an A-side component from an external source and to direct the received A-side component to the heater;
and the rest of the plurality of headers are adapted to receive B-side component from an external source and to direct the received B-side component to the heater.
