This invention relates to a valve assembly.
An object of the invention is to providean
assembly of the character described embodying

with a ?owway which may be brought into align
ment with the ?owway- of the casing to provide

trolling assembly including the cylindrical sleeve

assembly'being movable to another position’ to
close the ?owway through ‘the casing and being
expansible with means to expand the same to

is ?tted a tapering expander I16. This‘. expander

angles to the axis of the bore M.
The expander I5 is normally held in its outer
position by means of a pin 21 mounted in the

expander as shown more accurately in Figure .6.
