  • Patent number: 5620116
    Abstract: The invention relates to a rotary vane gate for free-flowing bulk material and Comprises a housing provided with housing covers on the end faces as well as with an inlet opening and an outlet opening and a compartmentalised wheel disposed in the housing with a rotatably mounted drive shaft, the wheel having compartments which are axially delimited by limiting plates 11. With a view to a construction which is particularly resistant to pressure shocks and is safe against penetration of flames, a sealed wear plate is provided between each limiting plate of the wheel and the neighbouring housing cover and at least one bypass chamber is provided between this wear plate and the limiting plate. The axial internal width of the inlet opening corresponds at most to the axial internal width of the compartments and the axial internal width of the outlet corresponds approximately to the overall length of the wheel including the bypass chambers.
