Abstract:
A showerhead includes a valve plate that is fixed in a housing and directs water received by the housing through apertures in the valve plate. A selector disk is coupled to and rotatable with respect to the valve plate. The selector disk has respective channels for conducting water from respective apertures at its rear to respective chambers at its front where different spray effects are produced. The respective apertures at the rear of the selector disk are selectably alignable to receive water from the apertures of the valve plate through rotation of the selector disk with respect to the valve plate, thereby producing the different spray effects based on the position to which the selector disk is rotated. A face plate is fixed to the selector disk and rotatable with the selector disk. The valve plate, selector disk and face plate are preferably joined by snap structures to reduce the axial length of the showerhead. The showerhead may be implemented as a stationary showerhead or a handheld showerhead.
Abstract:
A multifunction showerhead or hand held showerhead assembly, capable of providing a series of water spray effects. The primary components of the showerhead assembly are a fluid directing valve assembly which includes a pair of generally cup shaped members co-axially mounted with opposing end faces proximate to one another. One of the generally cup shaped members has a bottom surface defining a plurality of fluid flow passageways. When the second member is rotated in opposing relationship to the base of the first member, the fluid flow passageways direct the fluid flow from an orifice in the first member to a pair of outlet passages, or alternatively to a sealed chamber.
Abstract:
A device enables a user to selectively change the flow of water produced by a waterspout between aerated flow and non-aerated flow. The device is preferably implemented as an adapter that is threaded to or otherwise coupled to the end of a waterspout such as a kitchen or bathroom faucet waterspout or a bathtub waterspout. The device includes a closure mechanism that is operable by a user to permit or prevent aeration of water flowing through the adapter. The adapter may include a control ring that may be rotated by a user to selectively open and close bores for introducing air into the interior of the adapter. When the control ring is turned to an open position, air is introduced and an aerated water flow is produced. When the ring is turned to a closed position, air is not introduced and non-aerated or laminar flow is produced. A user is thereby enabled to select the desired type of flow.
Abstract:
A shower head that provides a series of spray effects. The shower head includes an inlet port to establish fluid communication with a source of water and at least two outlet ports to direct a spray with various effects to the user. A pushrod disposed in fluid communication between the inlet port and the outlet ports selectively opens the outlet ports to allow the user to continuously select any combination of spray effects, which may include a continuous stream or a pulsating jet. The pushrod is actuated by a rotating cam ring operated by the user. The cam moves the pushrod transversely across the inlet port and, under control of of the user, directs water from the inlet port to the outlet ports. The cam ring maintains the pushrod in the selected orientation.
