Abstract (en)
[origin: EP2664783A1] The pressure control valve system (100) has a main fuel line (103) which is closed with a spring-loaded sealing structure (105) for maintaining a fuel pressure in a fuel line (101). The sealing structure is comprised of a sealing structure head (107) for sealing the main fuel line, by pressing the sealing structure with spring force against a sealing seat (117). An auxiliary fuel line (109) is formed in the spring-loaded sealing structure for filling the fuel line with fuel. The spring-loaded sealing structure (111) is provided for sealing the auxiliary fuel line.
