摘要： An injection valve for fuel injection systems in internal combustion engines which comprises a movable valve element cooperating with a valve seat disposed in a nozzle body, with a guide bore provided downstream of the valve seat. A swirl insert is partially compressed in the guide bore and disposes open swirl channels in the direction of its circumference. The swirl channels extend in an axial direction from one end of the swirl insert to the other, are slanted toward the longitudinal shaft of the injection valve and discharge in a tangential direction into a preparation bore. The swirl channels serve simultaneously as metering channels whose throttling length is adjustable by displacing the swirl insert inside the guide bore.

摘要： An adjustment device having a servomotor and arranged for rotary angle adjustment is proposed. The rotary portion is connected via a shaft with a throttle device which controls the cross section of a bypass line bypassing a throttle valve disposed in the intake tube of an internal combustion engine. The adjustment device is axially limited on one end by a cap, which is embodied as a cast part together with a portion of the bypass line. The throttle device is embodied as a rotary slide and with a control portion transversely penetrates the cap and the bypass with the control portion arranged to open the bypass to a greater or lesser extent depending on the position of the rotary slide. Between an armature of the servomotor and the rotary slide, a sealing disc is loosely guided on the shaft. As a result of a pressure drop at the sealing disc, the sealing disc can be pressed against a sealing face of the cap in order to keep the leakage air quantity as small as possible.
