vention are designed particularly for use with 30
pumping elements and especially pumping ele
ments for liquid fuel. As shown in the present
instance, I, 2 and 3 are separate pumping ele
ments each having an inlet port 4 and an outlet
port 5. The pumping elements insofar as the .
present invention is concerned may be of stand
and construction.
The manifold assemblies for connection to the
inlet ports or the outlet ports are alike and there
fore but one will be described. In detail, the 40
manifold assembly has the hollow body 5 pro
vided with the longitudinal passage 1 which is
open at one end 8 and closed'at the other end 9.
The body is formed at opposite sides of the lon
gitudinal passage 1 with different sets of trans
verse holes which are arranged in pairs of ax
ially aligned holes I ll and H positioned longitu
dinally of the body for axial alignment with either
the inlet ports or the outlet ports. The body is
From the above description it will be readily
seen that a simple construction of manifold as
sembly has been devised for attachment to a plu
rality of pumping elements. It will be seen that
the means for securing the body of the manifold
assembly and placing the inlet ports or the outlet
ports of the pumping elements in communication
with the longitudinal passage of the manifold
assembly are located at one side of the longitu
dinal passage and therefore do not obstruct ?ow
through the longitudinal passage. The flow is
also kept smooth and free from eddies, surging
or other agitation resulting in a larger delivery
of liquid. As a result, the manifold assembly may
be of smaller cross section than those heretofore
45 made and at the same time take care of as great
amount of ?ow. It will also be seen that by hav
ing one end of the longitudinal passage closed
the direction of ?ow through the manifoldas
