Solenoid valve for controlling an electrically controlled fuel ignition valve

PCT No. PCT / DE97 / 01887 Sec. 371 Date Aug. 7, 1998 Sec. 102(e) Date Aug. 7, 1998 PCT Filed Aug. 29, 1997 PCT Pub. No. WO98 / 25025 PCT Pub. Date Jun. 11, 1998A solenoid valve including a magnet armature having an armature disk and an armature bolt that is guided in a sliding part. In order to prevent a postoscillation of the armature disk after a closing of the solenoid valve, a damping device is provided on the magnet armature. With a device of this kind, a required short switching time of the solenoid valve can be precisely maintained. The solenoid valve (30) is designated for use in fuel injection systems with a common rail.

Ball valve with integrated removable flow venturi, flow balancing means, and pipe union means

A valve assembly for use in heating, ventilating and air conditioning systems. The valve assembly includes a valve body having a chamber in which is rotatably mounted a quarter-turn flow control ball valve. A valve body nut having an outlet port is threadably mounted on the valve body adjacent the outlet end of the valve body chamber. A flow venturi is removably mounted in the inlet end of the valve body. A pipe union tailpiece is detachably mounted on the inlet end of the valve body. A pair of pressure / temperature readout ports are mounted on the valve body for use in determining the rate of fluid flow through the venturi. A vent plug is mounted on the valve body for venting air from the ball valve chamber.
