Pulsating jet spray head
First Claim
1. A shower head comprising:
- a. a housing forming a chamber defined in part by a plate having a set of fine spray supply ports, and a set of jet spray supply ports;
b. a peripherally engageable handle disk sealingly confronting and covering the plate, the handle disk having a set of fine spray nozzles and a set of jet nozzles, the handle disk being manually movable arcuately to connect the fine spray supply ports and fine spray nozzles, or to connect the jet spray supply ports with the jet spray nozzles;
c. means for producing a rotating current of water in the chamber;
d. and a rotor driven by the rotating water current, the rotor including a rotatable base plate disposed contiguous to the supply port plate, the base plate having closed and open portions movable past the supply ports in succession to produce at jet spray nozzles a pulsating effect.

Abstract
A spray head including a handle disk having an exposed front wall and manually engageable peripheral portion the wall having a set of jet nozzles arranged in a circle, the perforations having common communication with a set of fine spray nozzles; the handle disk being mounted for limited arcuate movement with respect to a housing having a mating perforated wall for exposing the jet nozzles or the perforations communicating with the spray nozzles. The interior of the housing forms a chamber in which water is caused to rotate and drive a rotor having at least one opening which passes intermittently across the jet nozzles or perforations depending on the position of the handle disk. When the jet spray nozzles are activated the effect of the rotor and its slot is to cause the jet nozzles to produce pulsating jets. When the fine spray nozzles are activated, the water entering the perforations is diffused to produce essentially constant flow through the fine spray nozzles.

11. A shower head comprising:
-
a. a housing forming a chamber having a single water inlet and deflector means adjacent said inlet for causing tangential deflection and rotation of water therein, a discharge plate having a ring of discharge ports, and a mandrel; b. a rotor including a hub journaled on the mandrel, a peripheral wall, radiating impeller webs joining the hub and wall, and a base disk also joining the hub and wall and confronting the discharge plate, a preselected arcuate portion of the rotor base disk having at least one opening and a complementary arcuate portion being closed whereby a preselected number of discharge ports are exposed and closed in sequence; c. a set of jet nozzles for the discharge ports adapted as the rotor slot passes the discharge ports to produce intermittent jets of water; d. a set of spray nozzles including pulsation damping means; e. and a manually operable control means for selectively connecting the jet nozzles or the spray nozzles with the discharge ports. - View Dependent Claims (12, 13, 14, 15, 19, 20)

a. a housing forming a chamber having a single water inlet and deflector means adjacent said inlet for causing tangential deflection and rotation of water therein, a discharge plate having a ring of discharge ports, and a mandrel; b. a rotor including a hub journaled on the mandrel, a peripheral wall, radiating impeller webs joining the hub and wall, and a base disk also joining the hub and wall and confronting the discharge plate, a preselected arcuate portion of the rotor base disk having at least one opening and a complementary arcuate portion being closed whereby a preselected number of discharge ports are exposed and closed in sequence; c. a set of jet nozzles for the discharge ports adapted as the rotor slot passes the discharge ports to produce intermittent jets of water; d. a handle disk overlying the discharge plate, and including a portion in sealing engagement therewith, penetrated by the jet nozzles; e. the handle disk also including a set of spray nozzles disposed centrally of the jet nozzles; f. the handle disk being arcuately movable to shut off the jet nozzles and connect the spray nozzles to the housing chamber. - View Dependent Claims (17, 18)
