Abstract
A vane assembly for use in a rotary vane actuator, the vane assembly comprising: a rotatable vane having a first side and a second side; a vane axle connected to the rotatable vane for converting pressure exerted on the rotatable vane into rotational motion; a vane seal on the first side of the rotatable vane, the vane seal being for sealing the rotatable vane; and a side-plate on the first side of the rotatable vane, the side-plate clamping the vane seal in position; wherein the side-plate comprises: an outer part providing an outer surface of the side-plate, the outer part defining an internal volume; and an inner part filling or substantially filling the internal volume defined by the outer part, the inner part being distinct from the outer part.
Claims22
A rotary vane actuator having a housing and a vane assembly, wherein:
- the housing has a cavity accommodating the vane assembly, the vane assembly dividing the cavity into a first chamber and a second chamber;
- and
- the vane assembly comprises:
- a rotatable vane having a first side and a second side;
- a vane axle projecting from the housing and being connected to the rotatable vane to convert pressure exerted on the rotatable vane into rotational motion;
- a vane seal on the first side of the rotatable vane, the vane seal providing a seal between the rotatable vane and the housing;
- and
- a side-plate on the first side of the rotatable vane, the side-plate clamping the vane seal in position;
- wherein the side-plate comprises:
- an outer part providing an outer surface of the side-plate, the outer part defining an internal volume;
- and
- an inner part filling or substantially filling the internal volume defined by the outer part, the inner part being distinct from the outer part.
