A tank has two substantially parallel side surfaces, a tank first side surface and a tank second side surface, and the return filter is provided in the tank via an insertion hole formed in the tank first side surface. The strainer has one end provided on an outflow portion provided on a bottom surface of a filter case and the other end provided on the tank second side surface.

A strainer for a fuel pump according to the present invention includes: a communicating pipe including a flow path formed to communicate with a fuel inlet of the fuel pump; a filter including an internal space in which a fuel flows and coupled to the communicating pipe so that the internal space communicates with the communicating pipe; and a rib disposed in the filter and coupled to the communicating pipe, in which the filter includes a first filtering portion extending in a length direction with respect to the communicating pipe, a connecting portion extending in a width direction at an edge of the first filtering portion, and a second filtering portion extending in the length direction at the connecting portion and spaced apart from the first filtering portion in the width direction. Therefore, the strainer may have a relatively large filtering area and a small size.

An in-tank filter bowl with a de-aeration shroud for a hydraulic or oil reservoir includes an outlet shroud surrounding the filter bowl outlet at a proximal end thereof and having a shroud fluid outlet at a distal end thereof with a larger opening than an opening of the filter bowl outlet. The outlet shroud may be formed as or include a diverging member surrounding the filter bowl outlet at a proximal end thereof and having a diverging member fluid outlet at a distal end thereof, wherein the member diverges from the proximal end to the distal end thereof. The outlet shroud may further include a central deflector positioned within the diverging member and combining with the diverging member to form an annular passage to the diverging member fluid outlet.

A dispensing container facilitates convenient chilling and dispensing of water, with a filtration arrangement provided to promote water purity. The system includes a generally cylindrical filter assembly positionable within a liquid container, so that the filter assembly is generally submerged in the water within the container. The filter assembly can be operably connected to a liquid spigot, so that when the spigot is opened, liquid within the container flows through the filter assembly and out of the container, through the opened liquid spigot. Convenient use by consumers is promoted by the provision of a filter protector, comprising a selectively removable, shrink-wrap sleeve surrounding the filter assembly. The shrink-wrap sleeve is positioned on the filter assembly to protect the assembly prior to removal of the shrink-wrap sleeve. A removable tape element is provided to temporarily connect the filter assembly to the spigot prior to use.

An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.

Methods and apparatus providing for the isolation of an unknown mutation from a sample comprising wild type nucleic acids and mutated nucleic acids through the application of time-varying driving fields and periodically varying mobility-altering fields to the sample within in an affinity matrix.

Anti-drainback valves, flex tube assemblies that include one or more anti-drainback valves, and fluid filters that include one or more flex tube assemblies and/or anti-drainback valves are disclosed. In embodiments the anti-drainback valves and flex tube assemblies are described in the context of their use in a multi (e.g. dual) pump fluid filter, such as a dual pump transmission fluid filter. Dual pump fluid filters including integral and separable flex tube assemblies are also described.

Liquid reservoir systems are disclosed. In one embodiment, a liquid reservoir system may capture and retain a fuel reservoir to provide an un-interrupted fuel supply to a fuel pump or pickup line during low fuel conditions such as those that may be experienced during vehicle acceleration, braking or side to side maneuvers. It may also capture and retain a fuel reservoir to provide an un-interrupted fuel supply to a fuel pump or other pickup line during periods of high agitation such as may be experienced during vehicle jumping, cross country/closed course racing and other aggressive driving maneuvers.

A pump assembly for a fluid tank extends along a longitudinal axis and includes a cover at an external end, the cover including a flange that extends radially outward of the longitudinal axis, an insertable end opposite the external end along the longitudinal axis, and a rotatable arm that is flexible such that, when the rotatable arm is resiliently bent such that the rotatable arm has a radial extent, from the longitudinal axis, that is less than the flange, the sender assembly is in a compact state in which the insertable end and the flange would be able to move straight along the longitudinal axis, which is coaxial with a center axis of an opening of the fluid tank, from a position where the insertable end initially enters the opening to a position where the flange engages the fluid tank.
