Patent number: 6216730Abstract: A diaphragm-type flush valve for use with toilet devices such as urinals and water closets includes a body having an inlet and an outlet. There is a valve seat between the inlet and outlet and a valve member movable to a closing position on the valve seat to control water flow through the flush valve. The valve member includes a diaphragm peripherally attached to the body and there is a pressure chamber above the diaphragm with water therein holding the valve member on said valve seat. An annular filter body is attached to the underside of the diaphragm at spaced locations thereon and there is a bypass orifice in the filter body positioned at one of the spaced locations. The filter body includes a plurality of peripherally spaced grooves and there is a filter ring mounted on the filter body and facing the grooves. The filter ring and grooves form a plurality of filter passages in communication with the bypass orifice and the flush valve inlet.Type: GrantFiled: June 8, 2000Date of Patent: April 17, 2001Assignee: Sloan Valve CompanyInventor: David C.

Patent number: 6189985Abstract: A rodlike magnet valve having a magnetic part which is surrounded by a coil for actuating the valve. The magnet valve can be inserted into a receiving bore of a hydraulic block of a slip-controlled vehicle brake system. For fast, economical manufacture of the magnet valve, the magnet valve has a rotationally symmetrical base body, which has a through bore and a securing flange, as an extruded part without undercuts or tapered features. Along with the advantage of enabling fast, inexpensive manufacture of its base body, the magnet valve has the further advantage that the base body can be made from an economical reforming steel, which can be readily welded for fluid-tight mounting of a valve dome.Type: GrantFiled: May 28, 1999Date of Patent: February 20, 2001Assignee: Robert Bosch GmbHInventors: Siegfried Fritsch, Martin Kirschner

Patent number: 6182689Abstract: A diaphragm assembly for use in a diaphragm type toilet room flush valve includes a diaphragm formed of a flexible material and adapted to separate an inlet and outlet of the flush valve. There is a bypass orifice in the diaphragm. A filter assembly is positioned on the flush valve inlet side of the diaphragm and upstream from the bypass orifice. The filter assembly includes a peripherally extending screen spaced from the underside of the diaphragm with the screen being secured to the diaphragm assembly about an inner peripheral portion thereof.Type: GrantFiled: July 14, 1999Date of Patent: February 6, 2001Assignee: Sloan Valve CompanyInventors: John W. Lauer, David C. Hall

Patent number: 6173739Abstract: Addow's FDC is different from current FDCs, because it is a FDC and a check valve in one. Addow's FDC saves labor and time when compared to the current FDC, because with current FDC, one has to install a check valve and then install the FDC. With Addow's FDC, it is a one step process. Addow's FDC is equipped with swivels which don't allow debris, garbage or trash to be deposited in the FDC and this makes Addow's FDC debris proof. Addow's FDC allows back flushing test to be performed by removing the 4 inch cap and reversing the FDC. Addow's FDC, unlike current FDCs, comes with three different styles of outlets, which are grooved, flange, and threaded. This gives the consumers more selections to suit their needs. Current FDCs come only with one style of outlet, which is threaded outlet.Type: GrantFiled: December 29, 1998Date of Patent: January 16, 2001Inventors: Abdul Addo, Ali Addo

Patent number: 6158455Abstract: A cap assembly for providing continuous drip to a faucet exposed to freezing temperatures such as a faucet located outside a house. The cap assembly includes a cap member adapted to be mounted over the end of a faucet, which cap member includes a cylindrical wall portion and a closed end portion having an opening therein. The cap assembly includes an internal annular ridge which is adapted to receive a flow disc within the ridge, which flow disc includes an opening which is non-aligned with the opening in the closed end portion of the cap in order to create a dripping action. A rubber washer is positioned in sealing engagement with the internal annular ridge and the flow disc. A filter member is located within the rubber washer such that, upon mounting of the cap assembly over the end portion of a faucet, a continuous dripping flow through the cap assembly may be provided in order to prevent water within the faucet or within piping leading to the faucet from freezing.Type: GrantFiled: August 6, 1998Date of Patent: December 12, 2000Inventors: William H. Marshall, Robert E. Williams
