<p>The injector has a high pressure chamber (61) separated from a valve chamber (62) using a valve seat (55), where the high pressure chamber is loaded with system pressure. The valve chamber is connected with a difference pressure chamber (33), and is separated from a low pressure chamber (63) using a valve seat (56), where the low pressure chamber is connected to a low pressure/return system. The valve seat (56) has a conical sealing surface that is formed at a valve piston (52) that presses a housing-sided valve piston seat (71) against the low pressure area.</p> |
