Abstract
A flow rectifier assembly including a manifold with a variable orifice disposed therein. Further, the flow rectifier assembly includes one or more valves disposed in the manifold and fluidly connected to the variable orifice to provide a uni-directional flow over the variable orifice. Each of the one or more valves includes a poppet. A fly-cut recess defined in the manifold includes a seat for resting the poppet.
Claims21
A flow rectifier assembly comprising:
- a manifold connected with a hydraulic line and a hydraulic cylinder assembly;
- a variable orifice disposed in the manifold;
- one or more valves disposed in the manifold, the one or more valves fluidly connected to the variable orifice and arranged to provide a uni-directional flow of hydraulic fluid through the variable orifice to and from the hydraulic cylinder assembly, at least one of the one or more valves including a poppet;
- and
- a fly-cut recess defined in the manifold, the fly-cut recess including a seat for resting the poppet.
A hydraulic suspension system comprising:
- a flow rectifier assembly including,
- a manifold,
- a variable orifice disposed in the manifold,
- one or more valves disposed in the manifold, fluidly connected to the variable orifice, and arranged to provide a uni-directional flow over the variable orifice, at least one of the one or more valves including a poppet, and
- a fly-cut recess defined in the manifold, the fly-cut recess including a seat for resting the poppet;
- a hydraulic cylinder assembly including a cylinder and a rod defining a head chamber and a rod chamber, the head chamber fluidly connected with the flow rectifier assembly;
- and
- one or more accumulators selectively fluidly connected with the flow rectifier assembly.
A hitch assembly for a machine, the hitch assembly configured to connect a first portion and a second portion of the machine, the hitch assembly comprising:
- an articulation hitch configured to pivotally couple the first portion and the second portion;
- and
- a hydraulic suspension system dampingly connected to the first portion and the second portion, the hydraulic suspension system including,
- a flow rectifier assembly including,
- a manifold,
- a variable orifice disposed in the manifold,
- one or more valves disposed in the manifold, fluidly connected to the variable orifice, and arranged to provide a uni-directional flow over the variable orifice, at least one of the one or more valves including a poppet, and
- a fly-cut recess defined in the manifold, the fly-cut recess including a seat for resting the poppet,
- a hydraulic cylinder assembly including a cylinder and a rod defining a head chamber and a rod chamber, the head chamber fluidly connected with the flow rectifier assembly, and
- one or more accumulators selectively fluidly connected with the flow rectifier assembly.
A flow rectifier assembly comprising:
- a manifold;
- a variable orifice disposed in the manifold;
- one or more valves disposed in the manifold, fluidly connected to the variable orifice, and arranged to provide a uni-directional flow over the variable orifice, at least one of the one or more valves including a poppet;
- a fly-cut recess defined in the manifold, the fly-cut recess including a seat for resting the poppet;
- and
- wherein the one or more valves are fluidly connected with the variable orifice in a bridge circuit.
