专利汇可以提供Cooling-gas circulators for nuclear-reactor power stations专利检索,专利查询,专利分析的服务。并且A circulator for pressurized gas in the cooling circuit of a nuclear-reactor power station is of a kind having an electric motor mounted in a wall-mounted pressure vessel, and a motordriven blower in the gas space at the inner end of the vessel and including guide vanes pivotally mounted in a gas passage of the impeller casing and adjustable to vary gas flow through the cooling circuit. Vane-adjusting gearing is afforded protection from the gas in the gas space by disposing said gas passage adjacent to the inner end of the vessel and mounting the gearing to extend within the vessel and through the vessel''s inner end.,下面是Cooling-gas circulators for nuclear-reactor power stations专利的具体信息内容。

1. A gas circulator comprising a tubular housing located in an opening in the wall of the pressure vessel of a nuclear-reactor plant to receive cooling gas from the pressure vessel; a motor in the housing; a wall closing the inner end of the housinG; a blower in the pressure vessel including an impeller, and guide vanes in an inlet passage adjacent the inner end wall and mounted on spindles for angular adjustment, the spindles extending through the inner end wall; and vane-control means located in the housing and operatively connected to the vane spindles.
2. A gas circulator according to claim 1, wherein the vane-control means include an oscillatable toothed ring, and the inner end wall of the housing is spaced inwards from the inner end of the motor frame so that the wall and frame form a gear chamber, and the wall is composed of a center portion and a hub portion and the oscillating toothed ring is mounted on the hub portion for oscillation in the chamber.
