The valve housing (4) is rotatable and moves on rotation the shaft-type projection (3). The housing is at least partially covered by a hood-type protection (5), which also has apertures (6). Out of these apertures extend the end parts of the shaft-type projections. An intermediate plate (7) between the regulator and the valve housing allows turning of the valve housing. A short tubular pin (8) is fixed to the valve housing so that a regulating lever can be inserted and rotate the valve housing. |
