Abstract:
Secondary fuel filter (143) provided downstream of a fuel pump (92) has a smaller pore size than a primary fuel filter (141) provided upstream of the fuel pump. The secondary fuel filter is covered with a case member (171) and positioned along a center frame (23) of the vehicle. The secondary fuel filter is made of non-woven fabric and formed in a bag shape, and fuel is filtered by the secondary fuel filter as it passes from the interior to the outside of the filter.
Abstract:
Filters principally for automatic swimming pool cleaners are detailed. The filters include bags of porous material formed into at least two lobes. At least one divider separates a primary flow path through the bags from multiple debris-collecting pockets.
Abstract:
A filter system for a container comprising a connector, an adjustable tube coupled to the connector and a filter coupled to said adjustable tube. The adjustable tube can be in the form of a corrugated tube or in the form of a telescoping tube. This system can be coupled to either the input or the output of a container.
Abstract:
A pool cleaner debris bag (18) having an access opening (24) and a closure means (25) operable to close the access opening (24) for collecting debris or open the access opening (24) for emptying debris from the bag (18). The closure means (25) includes a clamp member (50) having clamping edges (56) for squeezing together bag layers (28, 29) to close the access opening (24). The closure means (25) is buoyant in water for orienting the bag to avoid impeding cleaner body (6) travel.
Abstract:
An debris-capturing apparatus (10) having a fluid-pervious wall (12), an attachmentportion (14) attachable to the outflow port (22) of a pressure-cleaner device (20), and acollapsible inflow tube(16) that is substantially opened and made erect by the inflow of fluid butotherwise axially collapsed and thereby closed so as to block reverse flow of debris (25) throughthe outflow port (22). The erected inflow tube (16) preferably has cross-sectional flow areasalong its entire length approximating the cross-sectional flow area of the outflow port (22). Thedebris-capturing apparatus (10) is preferably integrally formed such that the inflow (16) tube is aturned-in extension of the attachment portion (14).
Abstract:
The invention relates to a method of providing an efficient separation and collection of pollutants in waste water by means of a separating and collecting apparatus (2). In first and second stages, respectively, of the filtering inner and outer liquid permeable filter containers (3 and 5, respectively) are used, which are formed of fabric (4 and 6, respectively) having comparatively more open and less open structure, respectively. The effective filtering area of both the first and the second stages extends substantially from an upper (2A) to a lower (2B) end of the separating apparatus (2) where they are integrated. A very high filtering capacity without any danger of clogging is obtained in this manner, by being able to separate and collect solid pollutants of different size over practically the entire filter surface in the different stages. A very high flow through capacity is thereby provided and maintained during a long period of time. The invention also relates to a separating and collecting apparatus (2) for providing such an efficient separation and collection of pollutants in waste water.
Abstract:
A method for manufacturing more particularly coffee filter bags from filter material such as filter paper. In order to reduce the amount of waste paper arising during the manufacture, this method comprises joining the two longitudinal strip edges of a strip of filter material that has a continuous longitudinal joint, so that a tube of filter material is developed, flattening the tube to a flattened tube having two superposed layers of filter material with two parallel longitudinal tube edges across from each other and two, in essence, flat outside surfaces lying across from each other and forming in the transverse direction of the flattened tube two filter bags side by side, which have first filter sides along the respective tube edges lying across from each other and have second filter sides turned towards each other.
Abstract:
The present invention describes a filter gasket (50) for removing debris from the hydraulic fluid in an internal combustion engine (10). An upper reservoir structure (30) is mounted on a front cover (14) of the engine (10) at interface (46). The front cover forms a lower reservoir (16). The upper reservoir structure (30) forms an upper reservoir (35). A gasket (42) is disposed along the interface (46) to seal the upper reservoir structure (30) to the front cover (14). A screen assembly (70) is positioned adjacent to the interface (46). The screen assembly (70) includes a filter screen (76) connected to a plate member (56). The plate member (56) operatively engages the gasket (42). The plate member (56) forces hydraulic fluid to pass through the filter screen (76), thus retaining debris that exceed the mesh size of the filter screen (76).
