Liquid Transferring Devices TRIZ Cases

A tank wagon dispensing system uses a bypass line and downstream valves to empty the pump and discharge line completely.

A motor-driven hose handling system uses a cable element to automate fuel dispenser hose retraction, reducing manual force and mechanical complexity.

Monitoring apparatus compares receipt data with probe measurements to detect suspicious fuel deliveries, eliminating costly physical inspections.

A vapor-tight refueling apparatus uses a dual locking mechanism to connect probe and receiver securely.

Mechanical valve assemblies in each tank shut off fuel flow automatically, eliminating spark risks from electrical sensors and reducing manual refueling time.

An integral plastic U-shaped spring on the piston rod eliminates metal components, simplifying recycling by removing disassembly requirements.

Parallel electromechanical valves segment flow control to resolve the trade-off between device complexity and flow adaptability.

Vacuum suction extracts water from fuel storage tanks, preventing microbial corrosion and costly maintenance shutdowns.

Segmented ribs and vertical flashings focus thermal energy on the bag seam, preventing overheating damage while ensuring reliable sealing under pressure.

A self-regulating flow control device secures hoses to recreational vehicle water tanks for hands-free operation.

Radial discharge ports on a rotating drum allow multiple servers to fill containers simultaneously, eliminating interference and boosting serving capacity.

A compact fuel shutoff valve merges check and cutoff functions into one casing to maintain tank pressure.

An automated timer and visual indicator ensure required contact time for sanitizing agents, preventing premature wiping that wastes chemicals.
