  • Horsepower limiter control for a variable displacement pump
    Patent number: 4076459
    Abstract: A horsepower limiter control for an axial piston pump provides a simple adjustment for setting the maximum horsepower the pump can provide and automatically adjusts the product of working pressure and maximum pump displacement to maintain the set horsepower. The horsepower limiter control operates to reduce the displacement of the pump when working fluid pressure exceeds the setting of the sequence valve.

  • Control system for variable displacement pumps
    Patent number: 4029439
    Abstract: In a hydraulic system having a plurality of variable displacement pumps driven by a prime mover, each pump has a variable ratio input device connected to a load sensing means. Each variable ratio input device automatically reduces the displacement of its respective pump by the same proportion when the prime mover is overloaded irrespective of the displacement setting of the pump and automatically increases the displacement of its pump by the same proportion up to the set displacement when the prime mover is not overloaded.

  • Low friction seal assembly
    Patent number: 3937130
    Abstract: A low friction seal assembly for a fluid energy translating device seals a pair of pressure fluid chambers from one another. The assembly is mounted in a movable member of the device and has an elastic member which mechanically and hydraulically biases a seal member into engagement with the walls of the device.
