    Abstract: A water filter cartridge has a cap with radially oriented first and second (either inlet or outlet) flow channels on first and second generally cylindrical portions. First and second seals encircle the first flow channel on the first portion and third and fourth seals encircle the second flow channel on the second portion. The second and third seals form a void volume during use which may be accessed by a vent path to eliminate moisture or to test for or indicate leaks. The radial flow paths reduce axial, push out forces on the filter cartridge and allow smaller locking tabs to be used. The first seal forms a top void volume during use which may be accessed by a vent path to eliminate moisture or to test for or indicate leaks.

  • Patent number: 9975059
    Abstract: A self-contained, portable, waste water evaporating apparatus is shown. A solar-operated submersible pump pumps waste water from just under the surface of a waste water pit, through a pair of automatic backflushing filters and out misters located around the bank of the waste water pit. At a predetermined pressure across the automatic backflushing filters, the automatic backflushing filters are reverse cycled, one at a time, to backflushing particles back into the waste water pit. Periodically, the misters are purged and/or cleaned to remove particles therefrom. In response to sunlight, solar panels provide DC voltage directly to the submersible pump. If pressure from the submersible pump gets excessive, a pressure relief valve removes the excess pressure.

  • Publication number: 20150001140
    Abstract: A water filtration system that includes a filter manifold having a rotatable cover is provided. A filter cartridge is provided that includes a sump having a filter head integrally secured to a first end and cap releasably secured to a second end. A locking mechanism extending from the cover locks into the filter manifold to position the cartridge in an “in-use” state. The filter cartridge further includes two offset cylindrical inlet and outlet members protruding from the filter head that are designed to engage corresponding inlet and outlets of the filter manifold through a horizontal engagement mechanism. A check valve is positioned within the filter manifold adjacent the inlet of the filter cartridge to control fluid flow through the water filtration system. The filter cartridge head includes fins upwardly extending therefrom that are configured to engage corresponding slots formed in a plurality of corrugated channels of the filter manifold.

  • Patent number: 8920649
    Abstract: An oil filter for an internal combustion engine has a filter housing having an interior and an exchangeable filter cartridge arranged in the interior of the filter housing. A drainage valve is arranged in the filter housing and has a valve seat and a valve member. The valve member is movable relative to the valve seat in an opening direction that is parallel and coaxial to a longitudinal axis of the filter housing and oriented toward the interior of the filter housing. The valve member is received in the valve seat in a closing direction opposite to the opening direction. The valve member can be pushed out of the filter housing in the closing direction. The valve member and the filter cartridge form together a servicing unit for joint exchange of the valve member and the filter cartridge.

  • Publication number: 20140366494
    Abstract: A fluid filter with a housing, a releasable cover, and a replaceable filter having a filter body and two end discs. The filter is plugged onto a housing pipe and a locking ring is guided on the pipe, preloaded in a push-out direction. The locking ring is locked in a pushed-out position by a locking device. An unlocking device guided by the filter unlocks the locking device when the filter is pushed onto the pipe and enables the locking ring and the filter to be pushed in. When the filter is fitted into the housing, a seal on the end disc or locking ring interacts with a housing sealing surface to separate an untreated filter side from a clean side. When the locking ring is in the pushed-out position and the filter bears against the locking ring, the seal is held away from the sealing surface of the housing.
