摘要:
A dispensing unit is provided having a circulation system for circulating a fluid in the dispensing unit. The circulation system includes a circulation circuit and a mechanism for circulating the fluid in the circulation circuit. By circulating the fluid, the fluid is counteracted from crystallizing. A method for circulating a fluid in a dispensing unit is also provided.

Foam dispenser systems, pumps and refill units are disclosed herein. A refill unit for refilling a foam dispenser system comprises a container for holding a supply of foamable liquid and a foam pump connected to the container. The pump incorporates a simple and inexpensive valve arrangement to move liquid through the pump and to create the foam. For example, a liquid foam pump may include a housing and a valve stem that moves in two directions. The valve stem has an inlet liquid pathway and an outlet liquid pathway to convey liquid to a mixing. In addition, a moveable valve body is movable by the valve stem in a first direction to move the valve body to the first position to open a liquid inlet pathway, and moveable in a second direction to move the valve body to the second position to open the outlet liquid pathway.

A dispensing system including a housing (10) with an interior bulkhead (18) and four progressive cavity pumps (20) mounted within the housing (10) on one side of the bulkhead (18). The pumps (20) are mounted with bores (25B) in vertical orientation. Gear boxes (28) including bevel gears coupling the vertically mounted pumps (20) with horizontally mounted motors (30) located on the other side of the interior bulkhead (18). A dispense head (40) is located above the housing (10) with outlet passages (50) extending from the pumps (20) to the dispense head (40) defining a path to the dispense head (40) which is continuously upward. The dispense head (40) includes valves (48) driven by a pneumatic cylinder (44). A solenoid (54) controls flow of pressurized air to the pneumatic cylinder (44) from a position adjacent the dispense head (40) on the boom (36) supporting both.

Assembly comprises a preferably collapsible liquid-product container (1), a pump (3) and tube (4) liquid-transporting system and a quick coupling device (5) for connecting the tube to the container, the coupling device comprising a suction (16) extending into the container, a mating tube-adaptor member - (7) and a non-return valve (17) in its passage. The system provides optimal user convenience and safety, allowing quick and safe connection of replacement liquid-product containers to the tube and pumping system.
摘要:
A system for the transfer of fluid in a vehicle includes a main tank (4), a secondary tank (5), a pump (6), a first valve arrangement (11) and a several fluid pathways (13, 15, 17). In response to a control signal, the system is placed into a first condition, in which the first valve arrangement (11) is in a first condition, in which the pump (6) transfers the fluid from the secondary tank (5) to the main tank (4) through the valve arrangement (11), or into a second condition, in which the first valve arrangement (11) is in a second condition and the fluid pathways are blown clean from fluid. Also, a method for transfer of fluid in a system intended for a vehicle is disclosed.
