Abstract
Abstract A valve, particularly a radiator valve, has a housing and a valve seat provided in the housing. An inlet and an outlet are located at opposite sides of the valve seat in the housing and flow regulating means is provided, including a body having a sealing surface and being mounted for one movement relative to the valve seat to thereby preselect a desired maximum value of a flow aperture between the latter and the sealing surface, and being further mounted for another movement relative to the valve seat to thereby decrease the flow aperture between the valve seat and the sealing surface at the will of a user from the preselected maximum value towards zero value.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
216 words
A valve, particularly for use for radiators, and the like, comprising a valve housing having an interior chamber bounded by a circumferential wall and provided with two spaced opposite apertures, one of which is an inlet, a valve seat between said apertures, and an outlet in said circumferential wall between said valve seat and the other of said apertures; a movable valve head arranged in said interior chamber of said valve housing movable between a closed position engaging said valve seat and an open position spaced therefrom, said valve body including flowrestricting means the flow-restricting action of which varies depending upon the angular position of said valve head relative to said valve seat; moving means passing through said other aperture for moving said valve head between said closed and open positions thereof; and adjusting means mounted on said valve head so as to be non-rotatable but axially movable with respect thereto, said adjusting means being angularly adjustable with respect to said housing and permitting in each of the adjusted positions thereof movement of said valve head only in axial direction by said moving means so that for each of said angularly adjusted positions of said valve head a different flow range is obtainable by moving the valve head axially between the closed and open positions thereof.
Claim 2
Dependent Claim
216 words
A valve, particularly for use for radiators, and the like, comprising a valve housing having an interior chamber bounded by a circumferential wall and provided with two spaced opposite apertures, one of which is an inlet, a valve seat between said apertures, and an outlet in said circumferential wall between said valve seat and the other of said apertures; a movable valve head arranged in said interior chamber of said valve housing movable between a closed position engaging said valve seat and an open position spaced therefrom, said valve body including flowrestricting means the flow-restricting action of which varies depending upon the angular position of said valve head relative to said valve seat; moving means passing through said other aperture for moving said valve head between said closed and open positions thereof; and adjusting means mounted on said valve head so as to be non-rotatable but axially movable with respect thereto, said adjusting means being angularly adjustable with respect to said housing and permitting in each of the adjusted positions thereof movement of said valve head only in axial direction by said moving means so that for each of said angularly adjusted positions of said valve head a different flow range is obtainable by moving the valve head axially between the closed and open positions thereof.
Claim 3
Dependent Claim
66 words
A valve as defined in claim 1, said valve seat including an annular wall surrounding a hole communicating with said inlet and said outlet, and an annular groove surrounding said annular wall; and wherein said flow-restricting means comprises an annular portion provided on said valve head and arranged to extend into said annular groove in response to movement of said valve head towards said closed position.
Claim 4
Dependent Claim
45 words
A valve as defined in claim 1, said adjusting means comprising an inner portion and an outer portion respectively located within and without said valve housing; and further comprising sealing means for preventing the escape of fluid between said housing means and said adjusting means.
Claim 5
Dependent Claim
17 words
A valve as defined in claim 3, wherein said sealing means comprises an O-ring of elastomeric material.
Claim 6
Dependent Claim
13 words
A valve as defined in claim 4, wherein said elastomeric material is rubber.
Claim 7
Dependent Claim
60 words
A valve as defined in claim 1, said adjusting means comprising a portion having a bore of polygonal cross-section and being turnably mounted in said housing; and said valve head having a section matingly guided in said bore for axial displacement therein between said open and closed positions, and four turning movement with but not relative to said adjusting means.
Claim 8
Dependent Claim
50 words
A valve as defined in claim 3, said adjusting means and said housing means having juxtaposed outer and inner surfaces, respectively, and one of said surfaces having a circumferential recess encircling said adjuSting means and in which said sealing means is received in sealing engagement with both of said surfaces.
