This invention relates to a double acting valve
tubular neck I0 which terminates in a ?shing
head I I at the upper end.
Fitted through the bushing 4 there is a tubular
assembly.
An object of the invention i's'to provide an
assembly of the character specially designed for
controlling the ?ow of liquid through a pipe in
a well and which, when in one position, will allow
sleeve I2 whose upper end is formed with a valve
seat I3 whereon the valve 9 may seat. This
sleeve is pinned in the bushing by means of a
frangible pin I4 so that the upper end of the
sleeve will extend above the bushing and its
lower end will extend beneath the bushing. The
10 pin' I4 is weaker than the pin 1. Secured to the
well liquid to enter the pipe while the pipe is
being lowered but will close the pipe against
the outlet of such liquid and when in another
position will prevent the entrance of well liquid
into the pipe.
The valve assembly has been particularly de
signed for use in certain types of packer setting
equipment although it is capable of general use
for controlling the flow of liquid through the 15
well pipe,
