“Low-dispersion quick release connector for hydraulic oil”
Quick couplings with poppet valves are widely used but are characterized by a certain level of oil leakage into the environment during the separation of the male connector from the female connector.
Alternatively, there are flat-faced connectors that have a very limited level of leakage but come with a significantly higher purchase cost.
The solution we developed at CAEB International has two objectives: on one hand, to maintain a production cost in line with the poppet connectors already on the market, and on the other, to significantly reduce the level of oil leakage into the environment.
The connector, which received the "Mention" at the EIMA 2024 Technical Innovation Contest, is characterized by the presence of a chamber capable of capturing hydraulic oil losses, which are then channeled back into the tractor's system using a combination of gravity and pressure.
Its operation is very simple: when the male fitting is inserted, the pressure pushes the residual oil into a tube connected to the female fitting, which directs it into the tractor’s system. When the male fitting is released, a mechanical system retains most of the oil inside the female fitting, preventing external leaks. Experimental measurements conducted with CREA in Treviglio, which assisted us in measuring the different levels of leakage of our connector compared to others already on the market, revealed that the CAEB International connector reduces oil leakage by over 80% compared to poppet connectors already available. In addition to the obvious environmental benefits, this coupling also provides cost savings due to the reduction in the need for the operator to top up the oil.
Equally significant are the advantages resulting from the fact that the operator does not need to maintain and periodically empty external oil collection tanks, as the fluid is channeled directly into the tractor's system.
A final noteworthy consideration is the easier connection/separation of the male and female connectors. The design of the two parts allows for a more precise, faster operation, requiring less effort from the operator.
