Abstract: A control system for operating fluid actuated components of a packer mechanism for a refuse collection vehicle comprising a fluid tank; a pump having an inlet communicating with the tank; a control valve having a main fluid passageway therethrough communicating at an inlet port thereof with the pump and at an outlet port thereof with the tank, a pilot fluid passageway therethrough communicating at an inlet port thereof with the pump and at an outlet port thereof with the tank, a first valve spool selectively operable for communicating the main fluid passageway with a component of the packer mechanism, the first spool being displaceable between a first position obstructing the pilot fluid passageway and a second position not obstructing the pilot fluid passageway, the first valve spool having a surface disposed normal to the axis thereof communicating with the pilot fluid passageway, and a second valve spool selectively operable for communicating the main fluid passageway with another component of the packer m

Abstract: A mechanism for operating a control valve mounted on a support structure and provided with slidable spools generally including a first control rod mounted on the support structure for rectilinear motion along its axis, a second control rod mounted on the support structure for rectilinear motion along its axis, means operatively interconnecting the first control rod and a first valve spool for translating the rectilinear movement of the first control rod to rectilinear movement of the first valve spool, means operatively interconnecting the second control rod to a second valve spool for translating the rectilinear movement of the second control rod to rectilinear movement of the second valve spool, a control actuator mounted on said support structure for pivotal movement about a first axis and for pivotal movement about a second axis generally perpendicular to said first axis, and means operatively interconnecting the control handle and the first control rod for translating the pivotal movement of the control

Abstract: A valve assembly comprising a body having a fluid passageway therethrough providing first and second ports, a floating valve seat and an engageable poppet disposed in the fluid passageway of the body between the ports thereof, means disposed on the body for yieldably biasing the valve seat into engagement with the poppet, means disposed on the body for yieldably biasing the poppet into engagement with the valve seat, abutment means disposed on the body engageable by the floating valve seat and poppet for restricting the movement of each of the floating valve seat and poppet toward the other thereof under the influence of the biasing means, the floating valve seat having a fluid passageway therethrough intercommunicating the first port and the poppet when the valve seat and poppet are disposed in engagement, the poppet having a primary fluid passageway therethrough intercommunicating the fluid passageway of the floating valve seat and the second port of the body when the valve seat and poppet are disposed in e

Abstract: A method of making a brake shoe having a curved table section and at least one rib section disposed on the concave side of the table section, generally including casting the brake shoe in a mold having cope and drag sections so that the axis of curvature of the table section thereof is disposed substantially parallel to the parting plane of the mold sections whereby no draft or parting ridge is formed on the outer curved surface of the table section.
