The manifold assemblies embodying the in body and the cap screws. 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 sembly may be readily changed by reversing the also formed with the recesses I2 at the inner ends 50 manifold assembly. of the holes I!) and adjacent the longitudinal pas What I claim as my invention is: sage 1.
