Valve with a turning head and non-return valves

摘要

The valve (1) has a rotatable rotary slide (7) provided with a conducting chamber, and an inlet attached to the conducting chamber. A set of outlets is individually attached to the conducting chamber independent of determined rotating position of the rotary slide. The conducting chamber is attached to a pressure chamber (23) over a non-return valve (57). A cylinder (25) is attached to the rotary slide, where the cylinder is brought into a borehole of the valve with a clearance fitting. An upper front side (31) of the cylinder forms a pressure chamber (49).
