Kitchen faucet side spray
First Claim
1. A spray device for use as an alternate water discharge to a faucet, said spray device including a body having a handle and a spray head, said spray head having first water discharge means and second water discharge means,a trigger movable on said body between an inoperable position, a first operable position, and a second operable position,a chamber within said body communicating with said first and second discharge means, a water passage in said handle communicating with said chamber, a piston movable within said chamber, a water passage within said piston connectable to said handle water passage,a stem within said chamber and connected to said trigger for concurrent movement therewith, said stem including a seal for closing said piston water passage from said handle water passage, spring means biasing said stem seal toward a piston water passage closing position, said stem and piston having interconnecting means thereon providing concurrent movement thereof,a flow diverter adjacent said first and second water discharge means, said flow diverter being movable by said piston between positions in which water flows from said piston water passage to either said first or second water discharge means,operation of said trigger from an inoperable position to said first operable position moving said stem seal to open the piston water passage and moving said piston and flow diverter to direct water through said first discharge means, movement of said trigger to said second operable position causing said piston to move said flow diverter to a position to direct water through said second discharge means.

Abstract
A spray device for use as an alternate water discharge to a faucet has a body with a handle and a spray head. The spray head has a first central water discharge in the form of a localized stream and a second peripheral spray type water discharge. There is a trigger which is movable on the body between an inoperable position, a first operable position, and a second operable position. In the first operable position water passes through the spray head central discharge and in the second operable position water passes through the peripheral spray. There is a chamber within the body which communicates with the first and second water discharges and there is a water passage in the handle communicating with the chamber. A piston is movable within the chamber and there is a water passage within the piston which may connect to the handle water passage. A stem is positioned within the chamber and is connected to and movable with the piston. The stem has a seal for closing the piston water passage. A coaxial spring biases the stem seal toward a piston water passage closing position. A flow diverter is located adjacent both water discharge passages, with the flow diverter being movable by the piston between positions in which water flows from the piston water passage to either of the first or second water discharges.
