| 摘要 |
The present invention concerns a liquid pressure reducing unit (1) for bringing in fluid communication with the ambient atmosphere a liquid contained in a pressurized container and for gradually decreasing the pressure of said liquid as it is being dispensed, said unit comprising: (a) A first half body (2a) comprising a contact surface and a first groove (3a) extending over said contact surface; (b) A flexible resilient sealing element (4) comprising a floor layer (4a) lining the floor of said first groove (3a), and (c) A second half body (2b) comprising a contact surface and a first and second opposed walls (2c, 2d) extending out of said contact surface and defining therebetween a second groove (3b), the contact surface of said second half body (2b) being joined to the contact surface of said first half body (2a), thus defining a fluid tight channel (3), said channel (3) being non rectilinear and/or having a cross-section varying over the length thereof. |
