摘要： In a self-cleaning filter assembly (10), a filter element (31) is fixed within a housing (17) and spaced from the peripheral wall (21) thereof by an annular solids collection space (34) in turn communicating with a solids outlet (63). An inlet (56) introduces pressurized liquid to be filtered circumferentially into the solids collection space. A shower assembly (81) rotates and includes an eccentric portion (84) having jets (91) aimed outward close to the inner surface of the filter element. Backwash liquid enters the rotating shower assembly under pressure for continuously pushing solids off the outer surface of the filter element as the shower assembly circumferentially advances. Filtrate from inside the filter element passes through a filtrate outletfromthe housing. A solids outletvalve (163) responds to a preselected increase in liquid pressure differential between the inlet and filtrate outlet to increase , venting of the annular solids collection space. A filtrate outlet valve (181) may simultaneously close to direct all liquid flow out the solids outlet. 1

摘要： A container such as a sump (28) having a bottom (32), at least one wall (33) extending upwardly from the bottom, and a flange (36) connected to the at least one wall and projecting therefrom. The flange preferably has apertures (37) extending partially into the interior portion of the flange from its exterior surface. The flange provides structural rigidity to the container and prevents irregularities from being formed in the walls during manufacture. Preferably, the container is a sump having four lower walls, four upper walls integrally connected to the lower walls by the flange, and four entrance walls integrally connected to the upper walls and defining a mouth for receiving fluids. The flange preferably has an upper surface having upper apertures and a lower surface having lower apertures that are axially aligned with the upper apertures. Pins may be utilized during manufacture of the sump by rotational molding to form apertures within the flange and aid in preventing irregularities from being formed.

摘要： An entry fitting having a cylindrical portion (36) and a conical portion (40) including a seal disposed about the body of the entry fitting. An axial displacement member (46) urges the seal along the conical portion to achieve a relatively wide range of sealing force. The entry fitting can include a shield (60) positioned on the exterior of a sump to provide an access space for displacement of the entry fitting toward the exterior of the sump to allow removal and replacement of the seal without first having to remove backfill from the exterior of the sump.

摘要： An adjustable length storage tank sump for attachment to an underground storage tank is provided. The storage tank sump is formed from a body having a polygonal lower portion with a chamber, an interconnecting conical middle portion, and an upper portion having a plurality of formations and an opening disposed thereon. The formations are axially spaced along the longitudinal axis of the body so that a predetermined number of the formations can be selectively removed during installation, thereby reducing the length of the storage tank sump. A sealing surface is provided on each formation so that a single seal can be installed on the formation closest the opening. An attachment structure, which is interchangeable among the formations, removably engages the formation closest to the opening. A removable lid for covering the opening is provided, the lid engaging the attachment structure such that the lid sealingly contacts the seal.

摘要： A control valve (18) for a holding tank (12) is provided for cutting off the flow of fluid into a holding tank device in response to achieving a predetermined fluid level in the holding tank. The assembly includes a housing (20) configured for placement adjacent a spill container. The housing has an upper inlet (25a) and a lower outlet (25b) and a flow passage therebetween having a diameter of which is substantially constant along its longitudinal length. A valve poppet (41) is situated within the flow passage and is axially rotatable between a substantially vertical, open position, that allows for the flow of fluid through the flow passage, and a closed position substantially blocking fluid flow through the flow passage when the holding tank has reached a predetermined level of fluid.
