20090107905 | Fluid filter seal - A filter assembly including first and second mating parts and a seal received in a groove of the first mating part. The seal includes a main body and a resiliently flexible, sloping skirt that extends from one side of the main body to a distal end spaced from the main body. The seal is sized so that the resiliently flexible skirt normally extends out of the groove of the first mating part when the skirt is not biased towards the main body. When the first mating part is slid against the second mating part, the second mating part causes the distal end of skirt of the seal to be biased into the groove and towards the main body of the seal. | 04-30-2009 |
20100116724 | REVERSE OSMOSIS WATER FILTERING SYSTEM - A valve assembly having a first valve defining an inlet connected to the inlet supply and an outlet connected to the concentrate chamber, a second valve defining an inlet connected to the permeate chamber and an outlet connected to the faucet, and a third valve defining an outlet connected to drain, a port connected to the concentrate chamber, and an inlet connected to the inlet supply. The port is selectively in fluid communication with the third valve outlet and inlet. When the faucet opens, the first valve opens, the second valve has permeate flowing, and the third valve opens a flowpath between the third valve port and the inlet due to pressure dropping in the second valve. When the faucet closes, the first valve closes and the third valve opens another flowpath between the third valve port and outlet due to pressure created in the second valve. | 05-13-2010 |
20110120928 | EASY CHANGE FILTER ASSEMBLY FOR REVERSE OSMOSIS MEMBRANE WATER PURIFICATION SYSTEM - A filter head including a lid extending along a central axis. The lid includes a filter bowl receptacle positioned coaxially about the central axis, a central receptacle positioned coaxially within the filter bowl receptacle, and an intermediate receptacle positioned coaxially between the central receptacle and the filter bowl receptacle. A conduit portion connects to the lid and extends along another axis that is normal to the central axis of the lid. The conduit portion includes a first pathway extending between the first end and the filter bowl receptacle, a second pathway extending between the first end and the central receptacle, a third pathway extending between the second end and the central receptacle, and a fourth pathway extending between the second end and the intermediate receptacle. Couplings allow the filter head to be pivoted about the central axis of the conduit portion. | 05-26-2011 |
20110180464 | SHUT OFF VALVE FOR A REVERSE OSMOSIS WATER FILTRATION SYSTEM - A shut-off valve for use in a reverse osmosis filtering system including a housing defining an interior in fluid communication with a water inlet, a water outlet, and a permeate inlet, the housing having a fluidic network with a flowpath that connects the water inlet and the water outlet, a diaphragm plate forming a portion of the fluidic network within the interior, a piston within the interior for selectively opening and closing the flowpath, and at least one diaphragm coupling to the piston and the diaphragm plate such that as permeate pressure changes occur at the permeate outlet, the piston rocks between opening and closing the flowpath based on deflection of the at least one diaphragm in response to the permeate pressure changes. | 07-28-2011 |
20150107019 | TOP-MOUNT TWIST-ON FAUCET - A top-mount faucet assembly includes a coupling mounted on a counter that selectively couples a faucet thereto. The counter coupling has a disc-shaped collar with two keepers and a land for selectively locking the faucet. The land has a v-shaped part and a n-shaped part. The faucet has a main valve body with a locking assembly. To couple the faucet to the counter coupling, the main valve body is placed over the coupling and turned clockwise so that slots align with the keepers to fix the faucet axially to the coupling. As the faucet rotates clockwise, the locking assembly rides along the v-shaped part until captured by the n-shaped part to lock the faucet in place rotationally. To uncouple the faucet from the coupling, a button is pushed so that the locking assembly moves radially inward out from the n-shaped part, then the faucet is turned counter-clockwise. | 04-23-2015 |
