text: The invention further comprehends the provision of a hydraulic valve structure having a body defining a valve chamber, a pressurized fluid inlet port opening to a midportion of the valve chamber, a first cylinder port opening to the valve chamber in spaced relationship to the inlet port, a second cylinder port opening to the valve chamber in oppositely spaced relationship to the inlet port, and a first outlet tank port opening to the valve chamber adjacent the first cylinder port, and a second outlet tank port opening to the valve chamber adjacent the second cylinder port, a spool reciprocably slidable in the valve chamber and having lands preventing communication through the valve chamber between the inlet port and either tank port in a neutral position of the spool, first solenoid means having a first plunger for selectively urging the spool in a first direction from the neutral position to cause concurrent communication between the inlet port and the first cylinder port and between the second cylinder port and the second outlet port, second solenoid means having a second plunger for selectively urging the spool in a second, opposite direction from the neutral position to cause concurrent communication between the inlet port and the second cylinder port and between the first cylinder port and the first outlet port, first biasing means for urging the spool in the first direction and the first plunger in the second direction, second biasing means for urging the spool in the second direction and the second plunger in the first direction, each biasing means comprising a tubular element defining a radially inner surface, an inner end, an outer shoulder on the tubular element inner surface, a biasing compression spring disposed coaxially within the tubular element and having an outer end abutting the outer shoulder thereon, the spring further defining an opposite inner end, a washer coaxially within the tubular element outwardly abutted by the inner end of the spring, and means on the tubular element removably retaining the washer in the tubular element, and a pair of shafts extending one each outwardly from the opposite ends of the spool, each shaft defining a distal end secured to an associated one of the plungers, a portion received in the associated one of the tubular elements and having a shoulder facing outwardly toward the outer shoulder of the tubular element, the washer outwardly abutting the shoulder and extending substantially fully between the shaft and the inner surface of the tubular element for reducing force exerted on the spool by fluid pressure in the valve chamber inwardly of the shaft shoulder.
