Abstract: A variable reciprocating pump assembly including a driven crank wheel, a crank arm coupled to and driven by the crank wheel the crank arm terminating at a wrist pin, a pump housing, and a piston is disclosed. The assembly may be adjustable to provide varied stroke length and pump capacity without affecting performance or drive properties.

Abstract: A dosing engine including a framework, fluid drivers, and a flow control device. The framework has an inlet that receives a fluid and an outlet that dispenses the fluid. The fluid drivers are supported by the framework and pump fluid toward the outlet. The flow control device is coupled to the framework and is in fluid communication with the inlet, the outlet, and the fluid drivers. The fluid drivers are cooperatively driven by a motive force from fluid flow through the inlet to dispense fluid via the outlet, and to drive the flow control device to distribute diluent to the diluent drivers in a coordinated manner.

Abstract: A fluid container cap includes a connection structure, a dispensing connector, and a movable restrictor that adjusts flow through the container cap is disclosed. A fluid container cap includes a connection structure, a dispensing connector, a restrictor, and a valve that is movably adjustable to alter fluid flow through the container cap is also disclosed.

Abstract: A closing engine including a framework, fluid drivers, and a flow control device. The framework has an inlet that receives a fluid and an outlet that dispenses the fluid.
