Abstract
Abstract The invention relates to a tap or valve, for use in an automobile heater system or the like, having a housing with a valve chamber therein, an inlet to the valve chamber, two outlets from the valve chamber one of which constitutes a by-pass, and an operating valve member mounted for arcuate movement in the valve chamber, the operating valve member having a crank and a flexible roller closure member mounted on the crank so as to be freely rotatable thereon, and the inner ends of the two outlets being spaced equally from the axis of arcuate movement of the operating valve member so that the flexible roller closure member may seat selectively on and close the inner end of either of the two outlets. Preferably the inlet to the valve chamber leads through the or a journal of the operating valve member, and the valve chamber is so shaped that the flexible roller closure member engages with part of the inner surface of the valve chamber as it travels from one outlet to the other.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
159 words
A valve comprising a housing having a valve chamber therein, first and second outlet passageways having inner ends which lead into said valve chamber, an inlet passageway intermediate said outlet passageways and having an inner end which leads into said valve chamber intermediate said inner ends of said outlet passageways, a crank comprising a crank pin, a first crank arm journalled in said housing and a second crank arm journalled in said inner end of said inlet passageway, said second crank arm having an inlet aperture therethrough which leads into said inlet passageway, a flexible roller on said crank pin which has a diameter sufficient to shut off the inner end of either of said outlet means and a control member secured to said first crank arm for controlling the position of said roller with respect to said inner ends of said outlet passageways so as to selectively control which of said outlet pipes is to receive flow therethrough.
Claim 2
Dependent Claim
159 words
A valve comprising a housing having a valve chamber therein, first and second outlet passageways having inner ends which lead into said valve chamber, an inlet passageway intermediate said outlet passageways and having an inner end which leads into said valve chamber intermediate said inner ends of said outlet passageways, a crank comprising a crank pin, a first crank arm journalled in said housing and a second crank arm journalled in said inner end of said inlet passageway, said second crank arm having an inlet aperture therethrough which leads into said inlet passageway, a flexible roller on said crank pin which has a diameter sufficient to shut off the inner end of either of said outlet means and a control member secured to said first crank arm for controlling the position of said roller with respect to said inner ends of said outlet passageways so as to selectively control which of said outlet pipes is to receive flow therethrough.
Claim 3
Dependent Claim
54 words
A valve as claimed in claim 1 wherein an inner surface of said housing of an arcuate shape lies between said inner ends of said outlet passageways and said roller engages and rolls upon said surface as said crank pin is moved between said inner ends of said outlet passageways by said control member.
Claim 4
Dependent Claim
38 words
A valve as claimed in claim 1 wherein said outlet passageways are coaxial, said inlet passageway is approximately centered between said inner ends of said outlet passageways and said roller is disposed substantially parallel to said inlet passageway.
Claim 5
Dependent Claim
54 words
A valve as claimed in claim 3 wherein an inner surface of said housing of an arcuate shape lies between said inner ends of said outlet passageways and said roller engages and rolls upon said surface as said crank pin is moved between said inner ends of said outlet passageways by said control member.
