    Abstract: A nozzle assembly includes a mixing channel and an aerator. The mixing channel has upstream and downstream ends defining a flow direction through the mixing channel and includes a housing wall and a mixer. The housing wall defines a flow passage and includes an inlet portion and a tip orifice. The inlet portion disposed at the upstream end and configured to receive a first material and a second material. The tip orifice is disposed at the downstream end and is configured to emit a plural component material from the mixing channel. The mixer is disposed within the mixing channel and is configured to mix the first material and the second material into the plural component material. The aerator is configured to flow nucleation air to a location downstream of an upstream end of the mixer and into a flow of the plural component material.

    Abstract: A plural component dispensing system 10 receives separate fluid components, mixes the components in a predetermined ratio, and dispenses the components as mixture. Each fluid component is supplied by a separate pump 12A, 12B to an individual variably controllable fluid regulator 14A, 14B. Each fluid component is supplied from its individual fluid regulator 14A, 14B through a flow meter 18A, 18B to a mixing device 20. The ratio of the components delivered to the mixing device 20 is controlled by the individual fluid regulators 14A, 14B based upon the flow rates measured by the flow meters 18A, 18B.

    Abstract: A fluid dispensing system includes a pump, a valve, and a dispenser disposed downstream of the valve and connected to the valve with a hose. To provide a steady flow rate at the dispenser, the pump charges the fluid to or above the pressure required to achieve a desired flow rate. The valve cycles between open and closed at a fixed frequency. The valve-open time is varied within that frequency to maintain the desired flow rate.

    Abstract: A progressive cavity pump includes a torque input disposed on a rotational axis, a resilient stator cylinder, a screw rotor situated within the resilient stator cylinder, and a universal joint. The universal joint rotationally couples the screw rotor to the torque input, and includes a swivel block, a linkage, a universal joint coupler, and a fastener. The swivel block has opposite laterally extending trunnions. The linkage extends parallel to the rotational axis, and laterally captures the laterally extending trunnions. The universal joint coupler is disposed around the swivel block and adjacent the linkage. The fastener connects the universal joint to the swivel block. The fastener and the laterally extending trunnions cooperate to transmit torque about the rotational axis through the linkage, while permitting lateral translation of the universal joint coupler in a plane orthogonal to the rotational axis.

    Abstract: A plural component dispensing system includes a dispensing device, first and second fluid component sources, a system controller, and an operator interface device. The first fluid component source is connected to the dispensing device to deliver the first fluid component to the dispensing device. The second fluid component source is connected to the dispensing device to deliver the second fluid component to the dispensing device. The system controller is connected to regulate operation of the first fluid component source and the second fluid component source to produce a target ratio of the first fluid component and the second fluid component at the dispensing device. The operator interface device is remote from and operatively connected to the system controller. The operator interface device is configured to output system state information received from the system controller and to receive operator input to control an operational state of the system controller.
