Patent Searching and Data


Title:
UNIT COMPRISING A MOVABLE ELEMENT AND A SPEED GOVERNOR
Document Type and Number:
WIPO Patent Application WO2001027491
Kind Code:
A3
Abstract:
A governor is disclosed which may be used to govern the speed or rotation of a shaft, such as a shaft (5) supporting a toilet seat lid (6). The shaft is provided with a portion having external threading (7), and a nut (9) is provided to engage the threaded portion of the shaft. The nut is constrained to permit the nut to move axially while preventing the nut from rotating. The nut is connected to means (14) which define part of a chamber so that rotation of the shaft moves the nut which consequently moves the means defining part of the chamber to alter the volume of the chamber. Means are provided defining a restricted air-flow passage communicating with the interior of the chamber. The chamber may comprise a bore having an air bleed valve (17) communicating with a closed end thereof, and the nut may be connected to a piston movable axially within the bore.
