1 Claim.
This invention relates to water lift pumps of
the non-piston type primarily for use as a source
of supply in domestic water systems.
Pumps of the character mentioned commonly
include a pair of gravity-fed water-receiving
chambers adapted to be submerged beneath the
water level in a Well and from which the water
is elevated by application of ?uid pressure to
the chambers alternately.

preventing discharge therethrough.

Two discharge pipes I3 and I9 communicate
with the bottoms of the chambers I3 and I4, re
spectively. In this instance both pipes I3 and I9
extend upwardly through the upper end head 23
of the‘ cylinder I0 and communicate with a sin
gle discharge pipe 2I controlled by a conventional
faucet 22. An outwardly opening check valve 23

in most instances it is the size of the floats re

In the pump shown this is accomplished
by the use of a valve 24 arranged to receive pres
sure ?uid from a suitable pressure tank 25
through a pipe 26 and operable to direct the ?uid
to the chambers I3 and I4, alternately, ‘through
pipes 2'5 and 28, respectively, which communi
