20100044299 | METHOD OF PREVENTING FILTER MEDIA CRACKING WHEN COMPRESSING TWO OR MORE FILTER MEDIA LAYERS - The present disclosure generally relates to injection molded thermoplastic single filter media layer and multi-filter media layer filter cartridges that include a novel arrangement of structural features to improve both the quality of the manufacturing process and the integrity of the filter media layer seal and more particularly to a process for manufacturing both single filter media layer and multi-filter media layer filter cartridges and to the single filter media layer and the multi-filter media layer filter cartridges produced thereby and even more particularly to a process for manufacturing a multi-filter media layer filter cartridge without cracking the upper most filter media layer or any filter media layer during the compressing of at least two porous filter media layers between an inlet and an outlet while insuring an effective seal and the multi-filter media layer filter cartridges produced thereby and, yet, more particularly, to single filter media layer and the multi-filter media layer filter cartridges using only a single inlet design configuration and a single outlet design configuration for manufacturing a plurality of different single filter media layer filter cartridge configurations and a plurality of different multi-filter media layer filter cartridge configurations. | 02-25-2010 |
20100282665 | FILTER CAPSULE - A filter capsule has a filter housing which, on at least one end face, has an end cap with an air release valve. A protective wall is formed on the end cap at a distance from the air release valve and protrudes beyond the air release valve. | 11-11-2010 |
20120187038 | PRESSURE FILTER DEVICE - A pressure filter device may include a filter housing having a filter housing pot and a filter housing cover connected to the filter housing pot in a pressure-tight manner. At least one filter element may be arranged in the filter housing. A vent line may be secured on the filter housing pot and connected to a crude-side gas collection region located directly beneath the filter housing cover to a tank. | 07-26-2012 |

20150129484 | VENTED FILTER CARTRIDGE FOR WATER TREATMENT DEVICE - A filter cartridge has a shell defining an upper portion with an upper interior volume and a lower portion with a lower interior volume. The cartridge is for use in gravity-fed water treatment systems having an upper untreated supply and a lower filtered container. A hydrophilic porous particulate carbon powder block filter in a polymeric binder is disposed in the cartridge. The filter has a central opening and is open on both ends. The top end of the block is fitted with an air vent tube. The lower end of the block is fitted into a rubber gasket to direct water flow into the lower container. As water flows through the filter cartridge, air is vented through the block filter central opening and out through the vent tube. | 05-14-2015 |
20150300524 | DEVICE FOR QUICKLY VENTING AND DRAINING A FILTER - The invention discloses an air vent valve for venting a filter, having a cavity with an inlet and an outlet and a sealing element in the interior of the cavity for sealing the inlet in a first position and for sealing the outlet in a second position. The sealing element is freely movable between the first position and the second position, and a flow is created between the inlet and the outlet when the sealing element is in an intermediate position between the first position and the second position. | 10-22-2015 |
20160074778 | Filter Element with Air Vent - A method and means are described for rapidly evacuating trapped air from the top of a top-loaded liquid filter housing. An air vent means is provided that prevents complete sealing between a bypass valve and a sealing surface on an endcap of a replaceable filter element. The air vent means enables the rapid evacuation of trapped air in the top of the housing chamber, but permits only a negligible flow rate of liquid, for example oil, through the air vent means once air is evacuated due to high viscosity ratio of liquid, such as oil, versus air. | 03-17-2016 |
