摘要： An injection system for internal combustion engines is proposed, in which once the engine has been turned off, a pressure equalization is established between the intake side and the pressure side of the high-pressure fuel pump. This prevents uncombusted fuel from reaching the combustion chambers of the engine. The pressure prevailing on the pressure side and the intake side when the engine is off furthermore assures that vapor bubbles cannot form, and this makes starting the engine easier.

摘要： The invention relates to a method for producing and securing a screw in a preset position to prevent unauthorized adjustment. The screw securing means according to the invention makes it possible to secure a screw connection in a simple manner, in that a screw head of thermoplastic plastic, which is at least partly located in a housing recess, is heated to such an extent that it changes to the liquid state, flows into the housing recess, and at least partially fills the housing recess. By form-fitting engagement with the threaded pin and the housing recess, security against twisting, and also against being rotated without authorization, is attained. Screws in components that vibrate severely, and adjusting screws that must not be adjusted by unauthorized third parties, can be secured with this screw securing means.

摘要： The invention relates to a high pressure fuel pump for a fuel injection system of an internal combustion engine, having a pump housing in which is formed a working space, into which fuel can be supplied from a low pressure region of the radial piston pump, the working space being delimited by a pump piston which can be driven, in order to pressurize the fuel, by an external drive, in particular by a camshaft of an internal combustion engine, wherein in order to meter the fuel quantity supplied to the working space, a throttle device having a variable throttle action is arranged on or in the pump housing.
