Abstract
A starting-valve throttle device has a housing having a housing recess which is configured therein and in which a switching member is repositionable between an evacuation position and a delivery position. The switching member in the evacuation position configures an evacuation duct which connects an entry duct to an evacuation opening. The switching member in the delivery position configures a passage duct which connects the entry duct to a delivery duct. A throttle member is disposed in the passage duct so as to be repositionable relative to the switching member. On account thereof, a melt flowing through the passage duct is capable of being throttled in a desired manner. The starting-valve throttle device is constructed so as to be simple, compact and reliable. The operation of the starting-valve throttle device and an associated screw extruder is simple and energy-efficient.
