<p>A pressure limiting valve has a control element (10) which can be acted on in an opening direction, against a first control face, by a pressure which is to be limited, and which can be acted on in a closing direction by a spring (16) and, against a second control face, by a control pressure prevailing in a control pressure space (14). The pressure prevailing in the control pressure space can be limited by means of a pilot control valve (21). A control fluid can be supplied to the control pressure space through the control element via a control fluid nozzle (48). Upstream of the first control face, a plate (38) is held on the control element. Formed between the plate and the first control face is a gap with a predefined gap dimension. Said gap is situated upstream of the control fluid nozzle.</p> |
