Only about 90% certain this is the exact one I have in my 3-compartment (would also like in my pre-rinse machine sink), but a Chicago Faucet pre-rinse sprayer. It seems very water-conservative with a jet nozzle end that tapers to a slower end - not like a shower head. Think of a single wave of spray with the top end stronger than the bottom end. Very useful, IMO. Easy to clean, too.
