摘要： A pump for fluent materials, and especially suitable for heavy and abrasive materials, has a piston in substantial clearance relation within a cylinder and operable in a pumping stroke to drive into a combination valving, wiping and sealing elastomeric ring about the discharge portion from the cylinder, so that the pumped material has minimal drag and wearing contact with relatively moving parts in the pump. The pump is adaptable for double action and proportional pumping.A self-reversing piston-driving fluid actuated motor is provided.

摘要： A spherical rocking and swivel member, within a chamber in a body having a passageway therethrough and extending in part through axially outwardly facing shoulder means therein spaced inwardly from one end of the body, thrusts toward the shoulder means and has a hollow coupling stem thereon projecting outwardly relative to one end of the body. The spherical member and the stem have a fluid passage therethrough in continuous fluid flow communication with the passageway. Combination packing ring and nut lock means seal the swivel member and adjacent end of the body and lockingly retains a retaining ring nut relative to the body. Bearing means facilitate rocking and swivelling movement of the spherical member relative to the shoulder means. A method of making the hose connector is also covered.
