Abstract
A device to provide a seal between a housing for a moving element such as a drill chain, piston or the like and the moving element. The device comprising a storage well to retain seal material, the block having an outlet connecting with an aperture in a housing enabling seal material to flow into the space between a housing and the moving element and form a seal, the device further including an inlet port enabling seal material precursor to be added into the block, and pressurising means to pressurise the seal material precursor and force it out of the aperture.
Claims15
A device to provide a seal between a housing 11 for a moving element such as a drill chain, piston or the like and the moving element,
- the device comprising a storage well to retain seal material, the well having an outlet connecting with an aperture in a housing enabling seal material to flow into the space between a housing and the moving element and form a seal,
- the device further including an inlet port (16) enabling seal material precursor to be added into the well,
- pressurising means to pressurise the seal material precursor and force it out of the aperture.
A method of producing a seal, the method comprising the steps of:
- (i) mounting a seal forming device to a casing, the device including a housing enclosing a portion of a reciprocating or rotating article with which a seal is to be made with the housing,
- (ii) the device having a storage well to retain a seal material, a closeable communicating aperture connecting the storage well with the external surface of an article, an inlet enabling seal material precursor to be introduced into the well, and pressurising means to apply pressure to the precursor;
- (iii) introducing flowable seal material precursor into the storage well,
- (iv) allowing the seal precursor to set into seal material,
- (v) applying pressure via the pressurising means to force the seal material through the aperture into the open volume between the housing and an article to seal the space between the housing and an article,
- (vi) introducing further seal precursor material to retain seal material in the storage well.
