20090045128 | Filter For Removing Sediment From Water - A system for removing sediment from water is disclosed. The exemplary embodiments described herein disclose a system comprising a filter chamber, having a deck positioned inside to divide it into an upper chamber and a lower chamber. The deck may have a plurality of holes to hold filtration elements and also may have a ridge or a skirt or both. An inlet line may be tangentially connected to the filter chamber and introduce influent liquid into the filter chamber below the deck and outside of the skirt. | 02-19-2009 |

20120298572 | Screen Intake Flow Control and Support Device - A screen intake has a central body with two screens attached on either end. Each of the screens has an interior that communicates with a hollow of the body via flow modifiers. These flow modifiers include one or more pipes disposed in the interior of the screens and through passages in ends of the body. A flow control support device disposed within the body supports the body's sidewall and divides the hollow into at least two portions—each communicating with flow from one of the flow modifiers. The device can include one or more plates disposed adjacent one another within the internal hollow with a peripheral edge attached to an inside of the body's sidewall. At least one of the one or more plates can be solid, or one or more of the plates can define openings therein allowing passage of at least some fluid therethrough. | 11-29-2012 |
20140061118 | DEVICE FOR THE SOLID/LIQUID SEPARATION OF SUBSTANCE MIXTURES AND SUSPENSIONS - Device for the solid/liquid separation of substance mixtures and suspensions, comprising a feed and at least one feed-side vertical filtration chamber ( | 03-06-2014 |
20140110330 | FILTRATION DEVICE - Provided is a filtration device with a plurality of filters that can be backwashed with purified water with a simple operation. The filtration device | 04-24-2014 |
20150114898 | Filter Element with a Bypass Duct as well as Filter Assembly with a Filter Element - A filter element for filtering a liquid medium has end plates and a filter material arranged between the end plates and flowed through by the liquid medium in a flow direction radial to a longitudinal axis of the filter element. A clean chamber is arranged in the flow direction downstream of the filter material and connected with an outlet of the filter element. A bypass duct for the liquid medium is provided that is fluidically connected by a bypass valve with the clean chamber. The bypass duct has an inlet in the first end plate. A support device is integrally formed on the first end plate and extends along the longitudinal axis away from the first end plate into the filter element interior. A sieve in the bypass duct separates solid materials from the liquid medium passing through the bypass duct. The sieve is attached to the support device. | 04-30-2015 |
20150136682 | FILTER DEVICE FOR FLUIDS - A filter device for fluids, having a connection member ( | 05-21-2015 |
20160129375 | SPOOL VALVE FOR DUAL FUEL BASE OPERATION FILTERS - A spool valve includes a cylindrical spool body defining porting for control of fluid flow through the spool body, the spool body having pockets on an outer surface and sealing inserts received within the pockets. The sealing inserts and the porting are configured to control fluid flow through the spool valve based on an alignment of the sealing inserts and the porting corresponding to rotational positioning of the spool valve within a valve housing. The spool valve may be incorporated into a filter head of a filter assembly including a first filter and a second filter. Based on the rotational position of the spool valve, the spool valve is configured to block fluid flow to and from one of the filters and permit fluid flow to and from the other of the filters, the sealing inserts providing a seal against the valve housing to prevent leakage from the blocked filter. | 05-12-2016 |
