Abstract:
A head for a water filter system having a filter element including a three-way valve member movable between a first position, a second position, and a third position. When the valve member is in the first position, incoming water is directed to the filter element to remove sediment and impurities from the water. When the valve member is in the second position, the incoming water is blocked from passing through the filter element and the valve member. Lastly, when the valve member is in the third position, the incoming water passes through the valve member and not the filter element so that the filter element can be removed and replaced without interrupting the incoming water flow.
Abstract:
A rotary valve spindle for flow control in the head of a filter includes a unitary dual function seal that is carried by the spindle and seals against the inner surface of the filter head during spindle rotation between flow and no-flow positions. The dual function seal greatly simplifies manufacture and assembly of the valve.
Abstract:
A valve assembly is disclosed for use in conjunction with a replaceable filter cartridge system. The valve assembly includes a head member having an interior valve chamber defining a central axis, and inlet and outlet passages extending parallel to and communicating with the interior valve chamber. The valve assembly further includes a valve member having an inlet path and an outlet path, adapted for rotation within the interior valve chamber of the head member between a filter position wherein the inlet path of the valve member is in communication with the inlet passage of the head member and a bypass position wherein the inlet path of the valve member is out of communication with the inlet passage of the head member. The valve assembly further includes a seal member seated in an upper surface of the valve member and positioned to seal against an opposing surface of the interior valve chamber. The seal member sealingly isolates untreated and treated fluid streams flowing through the inlet and outlet paths of the valve member, respectively, when the valve member is in the filter position, and sealingly isolates the inlet and outlet passages of the head member from the atmosphere when the valve member is in the bypass position to permit fluid to flow therebetween.
Abstract:
A rotary valve for directing fluid streams which has a circular stationary head having at least one and desirably multiple primary ports for connection with fluid streams at least one secondary port. The stationary head includes a number of first circular concentric channels formed therein and at least one second concentric channel. The first and second channels are associated with the primary and secondary ports, respectively. A rotatable head is provided having radial chambers, each having a first and second port for connection between a first channel and a secondary port. The rotatable head rotates against the stationary head and channels in a fluid sealed manner. An indexable drive rotates the rotatable head to interconnect predetermined primary channels and secondary ports. The timing of rotation can be continuous or intermittent depending upon the associated process of the fluid streams.

Abstract:
The present invention relates to a method and apparatus incorporating an automatic, three-way valve having inlet, outlet and drain passages and a close-open timing mechanism. The timing mechanism is adjusted to a predetermined period of time in order to close the drain passage and then open the outlet passage or vice-versa automatically after a predetermined period of time in response to the starting or stopping of an external source of pressurized fluid being directed to the three-way valve.
Abstract:
Regeneration of water treatment media is disclosed which includes a water treatment unit having one or more media therein, and which upon initiation of flow of the water, imparts turbulence and abrasion to the treatment medium to automatically cleanse the medium of light solid contaminants, as well as contaminant coatings on the media. This greatly improves the operation of the media and extends its life. In addition, the water treatment unit disclosed may simply be rotated through any one of a number of positions between service, backwash, flush, off, and/or bypass operational modes for further regeneration of the treatment media.
Abstract:
A floor mounted de-watering spin chamber is connected with a kitchen disposer-grinder for de-watering and collecting ground food scraps that are suitable for garden composts. The spin chamber contains a perforated rotary spin basket and has a rigid lid with a rigid inlet tube insertable in a rigid body so that only one latch is necessary to hold the lid securely on the spin chamber. A diverter valve operated by a manual knob controls the discharge of water and solid material from the disposer-grinder selectively through the spin chamber or a drainpipe and the knob also controls a switch for an electric motor driving the spin basket. The drain pipe may also receive water and solid material from a second sink which is not equipped with a disposer-grinder and which material is not treated by the present apparatus, a baffle in a pipe connection fitting preventing such material from backing up into the spin chamber.
Abstract:
A Filtering System which is capable of handling large quantities of coolants and the System includes a reservoir for filtrates as, for example, from metal-working machines. The filtrate is returned to such machines by a pump which draws some of it from the reservoir, passes it through an eductor and then returns it to the reservoir. In operation, suction is applied to the outlet side of the filters to cause flow through them. In addition, valve means are provided so that the pump discharge can be used to clean the filters.
