Abstract:
A dispenser ( 10 ) comprises a housing ( 20 ) defining at least three feed channels ( 23, 24, 25 ) and at least one dispensing channel ( 26 ), a spool valve ( 28, 30 ) with a spool ( 30 ) defining at least four flow passages ( 31, 32, 33, 34 ), a deformable sealing plug ( 40 ) in at least two ( 23, 24 ) of the feed channels and in sealing orientation with both the housing ( 22 ) and the spool ( 30 ), and a nipple ( 50 ) in at least the two feed channels ( 23, 24 ) of the housing ( 22 ) comprising the sealing plugs ( 40 ); wherein the spool ( 30 ) can reversibly rotate between an open orientation and a closed orientation can dispense two-component foam formulations and purges the dispensing channel when in the off position.

Claim (Index 9):
A method of using the dispenser of  claim 1 , the method comprising: (A) simultaneously supplying under pressure: (i) a liquid isocyanate component into a first feed channel of the housing through the flow channels of a nipple and plug residing in the first feed channel; (ii) a liquid polyol component into a second feed channel of the housing through the flow channels of a nipple and plug residing in the second feed channel; and (iii) a gas into a third feed channel of the housing; (B) positioning the spool of the dispenser to allow the liquid isocyanate component to flow through the first flow passage of the spool, the polyol component to flow through the second flow passage of the spool and the gas to flow through the third flow passage of the spool; and (C) dispensing a combination of the isocyanate component, polyol component and gas out from the dispensing channel of the housing.
