摘要： A fluid filtering device has a housing with a mounting mechanism disposed at the forward end and on the top surface of the housing. A fluid inlet is defined through the housing top surface, and at least one fluid outlet is defined through the housing bottom surface. A valve member is disposed within the housing between the fluid inlet and the fluid outlet. At least one filter is disposed longitudinally within a portion of the housing rearward of the mounting mechanism. The filter is in fluid communication with the fluid inlet and a fluid outlet and may be removable from the rear of the housing. An actuator extends from the forward end of the housing and is connected with the valve member through the housing. The actuator moves the valve member between a filtered and unfiltered position. In the filtered position, fluid is directed from the fluid inlet and through the rear portion of the housing containing the filter. Upon mounting of the filtering device to the end of a supply member, the portion of the housing containing the filter extends rearwardly from the end of the supply member and is disposed longitudinally adjacent to the supply member.

摘要： The present invention provides a fluid dispenser. The flow of either filter or unfiltered fluid may be selected by positioning an actuator that also contains the filter. Selection is accomplished by positioning the actuator within two planes that are not coincident, or by positioning the actuator along a single axis.

摘要： An integrated filter for removing impurities from a fluid stream. The filter includes a first element adapted to remove at least some of the impurities by physical adsorption, and a second element adapted to remove at least some of the impurities by electrokinetic adsorption. Either or both of the first element and the second element further may be adapted to remove at least some of the impurities by sieving. The first element generally may be composed of loose particles or granules, or the first element may be composed of a porous block of an adsorbent, wherein the block is permeable to fluids and has interconnected pores therethrough. The second element generally is composed of a porous, charge-modified fibrous web which includes fibers prepared from a thermoplastic polymer. For example, the thermoplastic polymer may be a polyolefin. As another example, the porous, charge-modified fibrous web may be a nonwoven web, such as a meltblown or microfiber glass web. Alternatively, both the first and second elements may be in the form of a sheet.
