Abstract
Abstract A sanitary control valve, here constituting two valves sharing a common housing, includes a tube that is selectively radially compressed between a reaction surface on the housing and a movable cam surface disposed therein. The valve includes drag means which frictionally engage the cam, a series of teeth or serrations carried on one of the cam and housing for cooperation with means on the other of said cam and housing to provide discrete incremental positions of the cam. The knob has a pointer portion which overhangs a series of position indicia on the housing.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
85 words
A sanitary control valve assembly comprising: a. a housing having a pair of internal spaced reaction surfaces directed in the same direction; b. a pair of radially resilient tubes each arranged in a U-shape and respectively arranged about said reaction surfaces, the one U-shape being disposed about the other U-shape; and c. a pair of manually rotatable cams carried by said housing, and each having a camming surface respectively coactive with one of said reaction surface for individually collapsing said tubes by a selected amount.
Claim 2
Dependent Claim
85 words
A sanitary control valve assembly comprising: a. a housing having a pair of internal spaced reaction surfaces directed in the same direction; b. a pair of radially resilient tubes each arranged in a U-shape and respectively arranged about said reaction surfaces, the one U-shape being disposed about the other U-shape; and c. a pair of manually rotatable cams carried by said housing, and each having a camming surface respectively coactive with one of said reaction surface for individually collapsing said tubes by a selected amount.
Claim 3
Dependent Claim
45 words
A valve assembly according to claim 1, comprising; guide means in said housing defining a pair of separate channel-like passages within which said tubes are respectively radially constrained, a portion of said guide means having oppositely directed surfaces respectively defining part of said separate passages.
Claim 4
Dependent Claim
37 words
A valve assembly according to claim 2 in which at least one of said cams has a radially extending stop engageable with abutment surfaces on oppositely disposed portions of said tube guide means to limit cam movement.
Claim 5
Dependent Claim
65 words
A valve assembly according to claim 1 which includes at least one series of teeth disposed within said housing and carried by one of said housing and one cam and engaged by means disposed within said housing and coactive with said teeth, and said means being carried by the other of said housing and said one cam, to define incremental positions for the associated cam.
Claim 6
Dependent Claim
30 words
A valve assembly according to claim 4 which includes a spring acting to urge the associated cam axially and thereby urge said coactive means into firm engagement with said teeth.
Claim 7
Dependent Claim
29 words
A valve assembly according to claim 1 including at least one resilient blade carried by and within said housing and being loaded against said one cam at its periphery.
