Abstract
A fluid distribution system and method for mobile applications. The system includes a power source, a pump driven by the power source, and a motor driven by the pump. The system also includes a spray head with a fluid inlet passage, a fluid outlet passage, a fluid piston disposed in a chamber for controlled access between the inlet and outlet passages and defining a variable orifice, and a hydraulic cylinder controllably engaged to the orifice. The fluid piston and the hydraulic cylinder are aligned with a common longitudinal axis, and the inlet passage is offset from the axis in a direction opposed to the location of the outlet passage.
Claims20
A spray head for a fluid distribution system comprising:
- a fluid inlet passage;
- a fluid outlet passage;
- a piston disposed in a chamber of a spray head body for controlled access between the inlet and outlet passages and defining a variable orifice;
- an internal diverter joined to the piston and is within the variable orifice, wherein the internal diverter is disposed in the inlet passage when the variable orifice is closed;
- and
- a double acting hydraulic cylinder controllably engaged to the orifice.
A fluid distribution system, comprising:
- a power source;
- a pump driven by the power source;
- a motor driven by the pump;
- and
- a spray head configured to receive fluid from a fluid source associated with the motor, the spray head including;
- a fluid inlet passage;
- a fluid outlet passage;
- a piston disposed in a chamber of a spray head body for controlled access between the inlet and outlet passages and defining a variable orifice;
- an internal diverter joined to the piston and is within the variable orifice, wherein the internal diverter is disposed in the inlet passage when the variable orifice is closed;
- and
- a double acting hydraulic cylinder controllably engaged to the orifice.
A spray head for a fluid distribution system comprising:
- a fluid inlet passage;
- a fluid outlet passage;
- a piston disposed in a chamber of a spray head body for controlled access between the inlet and outlet passages and defining a variable orifice, wherein the piston is oriented within the chamber such that there is a blow-by gap between the piston and the spray head body around the circumference of the piston of at least about 0.25 mm;
- an internal diverter joined to the piston and is within the variable orifice, wherein the internal diverter is disposed in the inlet passage when the variable orifice is closed, and wherein the internal diverter has a surface facing the inlet passage and the ratio of the area of said internal diverter surface to the area of the inlet passage is 2:3 and about 1:10;
- and
- a double acting hydraulic cylinder controllably engaged to the orifice.
