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 1):
A dispenser ( 10 ) comprising:\n (a) a housing ( 20 ) with a feed end ( 21 ) and an opposing dispensing end ( 22 ), the feed end having defined therein at least three feed channels ( 23 ,  24  and  25 ) and the dispensing end having defined therein at least one dispensing channel ( 26 ); (b) a spool valve mounted in the housing between the feed end and dispensing end, the spool valve comprising a spool ( 30 ) with separate first, second and third flow passages ( 31 ,  32  and  33 ) and a fourth flow passage ( 34 ) that optionally intersects the third flow passage, where the flow passages are defined through the spool and each flow passage has a feed end opening ( 31 a ,  32 a ,  33 a  and  34 a , respectively) and a dispensing end opening ( 31 b ,  32 b ,  33 b  and  34 b , respectively), the spool has at least four gasket grooves ( 38 a ,  38 b ,  38 c  and  38 d ) defined circumferentially around the spool and in each of which a gasket ( 100 a ,  100 b ,  100 c  and  100 d , respectively) resides so that each gasket presses against the spool and housing to form a seal around the circumference of the spool with a gasket groove defined on each side of the feed end opening and dispensing end opening of each of the four flow passages such that the feed end opening and dispensing end opening of the third and fourth flow passages residing between the same two gasket grooves while the first flow passage feed end opening and dispensing end opening are the only flow passage openings of the four flow passages residing between one pair of gasket grooves and the second flow passage feed end opening and dispensing end opening are the only flow passage openings of the four flow passages residing between a second pair of gasket grooves; (c) a deformable sealing plug ( 40 ) in at least two feed channels positioned so as to be in a sealing orientation with the housing about the feed channel so as to prevent fluid communication through the feed channel around the sealing plug, the sealing plug having opposing spool end ( 41 ) and feed end ( 42 ) and a flow channel ( 43 ) extending through the sealing plug and through the opposing ends of the sealing plug, wherein the spool end of the sealing plug is pressing against and is in sealing contact with the spool, the entire sealing plug being elastomeric and deformable; and (d) a nipple ( 50 ) in each of at least the two feed channels of the housing containing sealing plugs and extending inside and out from the feed end of the feed channels, the nipples having opposing entrance end ( 51 ) and exit end ( 52 ) and a flow channel ( 53 ) extending through each nipple, including through the exit and entrance ends, the nipples oriented such that the exit end of a nipple presses against the feed end of a sealing plug within the feed channel of the housing and such that the flow channels of sealing plug and nipple are in fluid communication, the nipples being free of screw threading that screws the nipple into the feed channel; wherein the spool can reversibly rotate between: (i) an open position where each of the three distinct flow passages through the spool aligns in fluid communication each with distinct feed and dispensing channels of the housing with the first and second flow passages through the spool achieving fluid communication with a feed channel of the housing through a flow channel of a sealing plug and nipple and through a dispensing channel; and (ii) a closed position where the first and second flow passage through the spool are not in fluid communication with a feed channel of the housing and the fourth flow passage is in fluid communication with feed and dispensing channels of the housing that the third flow passage was in fluid communication with when in the open position.
