<p>The clutch mechanism operating in two modes, suitable for servo-drive of the water valve with a manual alternative control in any time interval, consists of the basic clutch body (4), of the clapper (5) closed to alternative control and of the driving body (17). This solution enables a simplification of actions related to the manual control. This aim is reached based on this principle, that the transversal driving arm (22) of the clapper (5) is end-bearing to the bottom (21) having a shape of the flat "V" closed to the undercut (18) and under this undercut, there is a bearing (12) hole located on the cylindrical end (11) of the clapper (5), while the bearing hole (12) is outgoing to the driving hole (10) located in the shaft (9) of the fundamental clutch body (4), in the front part (14) of which, there are engagement elements (13) for the opposite engagement elements (15) of the driving body (17), together with contact segment surfaces (20) for the opposite annular sealing pl ane (16) closed to the driving body (17).</p> |
