Abstract: A mix chamber for a plural component sprayer is configured to receive first and second component materials and emit a spray of a resulting plural component material. The mix chamber includes a chamber body extending between a first end and a second end and including flat lateral sides. A ramp feature is disposed proximate the first end and is configured to contact and push first and second side seals, respectively, away from a body axis as the mix chamber shifts in a first direction through a cartridge bore to increase a gap between the first side seal and the second side seal such that the first side seal engages the first flat lateral side and the second side seal engages the second flat lateral side.

Abstract: A fluid cartridge for a plural component sprayer is configured to receive first and second component materials and purge air from the sprayer and provide the first and second component materials and purge air to a mix chamber for spraying. The fluid cartridge includes a cartridge body, material flowpaths extending from a second end to a cartridge bore, and a purge path extending from the second end to the cartridge bore. Fluid checks are disposed in the material flowpaths and purge path to prevent backflow out of the fluid cartridge. Side seals are disposed in the material paths and are pre-loaded to extend into the cartridge bore and engage a mix chamber within the cartridge bore.

Abstract: A method of regulating a temperature of a fluid within a hose of a fluid dispensing system includes passing the fluid through the hose and across a heating element. A temperature of the fluid in the hose is sensed by the heating element. The sensed temperature of the fluid in the hose is compared to a reference temperature. An input of the heating element is adjusted in response to the comparison of the sensed temperature of the fluid in the hose to the reference temperature such that the temperature of the fluid is adjusted towards the reference temperature.

Abstract: A plural component dispensing system includes at least one compressed gas pneumatically connected to supply pressurized gas to each of a first pressure vessel that discharges a first fluid component and a second pressure vessel that discharges a second fluid component. Each of the first fluid component and the second fluid component is supplied from the respective pressure vessel through individual flow meters to a device. A first pressure regulator is pneumatically connected between the first pressure vessel and the at least one compressed gas source to regulate pressure of the first pressure vessel. A controller receives sensed first and second volumetric flow rates from the individual flow meters and controls the first pressure regulator based on the sensed volumetric flow rates to produce a target ratio of the first fluid component and the second fluid component at the device.

Abstract: A feed assembly for a melter includes a funnel, an inlet into the funnel, and a fan baffle situated atop the funnel. The funnel is oriented along a vertical axis, and has a funnel surface that narrows towards an outlet into the melter. The inlet is angled tangent to and downward towards the funnel surface to inject meltable pellets onto the funnel surface in a vortex pattern. The fan baffle is situated atop the funnel, and has a plurality of blades angled to oppose the vortex pattern so as to permit airflow but redirect the meltable pellets from the inlet towards the funnel surface.

Abstract: A pump system for pumping a fluid includes a motor housing, a motor, a rod, a positive displacement pump, a position sensor, and a controller. The motor is located within the motor housing. The rod is connected to and driven by the motor and the positive displacement pump for moving a fluid is driven by the rod. The position sensor produces a rod position signal that is a function of a position of the rod, and the controller produces a drive signal for driving the motor as a function of the rod position signal.

Abstract: First and second fluid components are individually pumped to a device from first and second pumps. A first volumetric flow rate of the first fluid component discharged from the first fluid component is measured. A second volumetric flow rate of the second fluid component discharged from the second pump is measured. Operation of at least one of the first and second pumps is controlled based on the measured first volumetric flow rate and the measured second volumetric flow rate to produce a target ratio of the first fluid component and the second fluid component at the device.

The collar has an internal bore coupled to the housing at a rotatable connection so as to permit a tube to extend from the sealed bore through the collar. The threaded engagement is disposed on the internal bore to receive a threaded pour spout.

Abstract: The fluid section or head (10) for a plural component applicator can be easily assembled or removed from the air section (12) by turning the fluid head ? of a turn. The fluid head (10) has four tabs (14) that protrude and engage with four undercut features (16) within the handle (12).

A locking tab feature (20) in the hose manifold (24) mates to a recess feature (22) in the handle (12) to prevent the fluid section (10) from rotating.
