Abstract
A transfer tube assembly comprises a transfer tube slidably engaged in sealing engagement with a first component. The transfer tube has a shoulder engageable with a stopper for limiting relative axial movement between the transfer tube and the first component. The shoulder has an abutment surface facing a corresponding bore surface of the first bore of the first component. The abutment surface and the bore surface are configured to generate axially opposing reaction forces in response to the abutment surface and the bore surface contacting each other.
