Locking Coupling

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a locking coupling system consisting of two identical coupling units that can be joined both mechanically and fluidically. Each unit contains a locking device for physical connection and a valve mechanism that enables or blocks fluid (liquid or gas) flow when the units are connected. The actuation of a single control element allows a user or a device to simultaneously lock the couplings together and open the fluid passage, making connection and disconnection safer, more reliable, and less complex.

Use CasesContent extracted from patent full text and abstract with AI.

• Satellite refueling in orbit, where safe coupling and decoupling of fuel lines is critical.
• Spacecraft modular assembly or reconfiguration (e.g., joining/decoupling propulsion or life support modules).
• Aerospace and aircraft fluid line connections, especially where remote actuation or quick, leak-free connections are needed.
• Industrial or chemical process equipment requiring secure, leak-proof fluid connections.
• Tank or gas container connections where safety and leak-prevention are crucial (e.g., medical gases, hazardous chemicals).

BenefitsContent extracted from patent full text and abstract with AI.

• Ensures both mechanical and fluidic connections are made or released in a single operation, reducing human error.
• Minimizes fluid leakage during connection or disconnection, providing enhanced safety and cleanliness.
• Identical (androgynous) units simplify design, inventory, and compatibility (units can mate in any combination).
• Designed for both manual and automated operation, increasing versatility in various environments (including space or hazardous zones).
• Robust sealing mechanisms to prevent contamination and ensure high reliability in critical applications.

Patent Abstract

The invention relates to a locking coupling (1) comprising a first coupling unit (11) and a second coupling unit (12), which in each case extend along a longitudinal axis (A) and are designed to be identical. Each coupling unit (11) comprises a valve unit (112) and a locking unit (111). The first and the second valve unit (112, 122) are designed to form a fluid connection between the first and the second coupling unit (11, 12), and the first and the second locking unit (111, 121) are designed to connect the first coupling unit (11) and the second coupling unit (12) mechanically to one another. The first coupling unit (11) comprises an actuating element (1114), by actuation of which the first and the second coupling unit (11, 12) can be mechanically connected to one another via the first and the second locking unit (111, 121) and can be fluidically connected to one another via the first and the second valve unit (112, 122).
