摘要： An override control, for a variable displacement pump having an actuator system which shifts the pump between a maximum displacement condition and a minimum displacement condition with the actuator system having a control device responsive to a primary source of pressurized fluid which is dependent upon operation of a prime mover drivingly connected to the pump, including a passage in communication with the actuator system and a secondary source of pressurized fluid selectively connectable to the passage and operable independently of the prime mover to override the control device causing the actuator system to shift the pump to one of the extreme displacement conditions.

摘要： A variable displacement pump of the type having a plurality of rotatable, axially-aligned pistons guided by a pivotal swash plate for enabling adjustment of displacement and also having a variable cutoff pressure compensator control means whereby the swash plate is variably shifted to its minimum displacement position so as to achieve a variable cutoff of pump flow. The pressure compensator control means also shifts the swash plate to its minimum displacement position when a predetermined maximum pressure is reached or when the pump load is in a neutral condition, thereby curtailing heat generation and horsepower loss.

摘要： Using a variable displacement pump as a source of pressurized fluid in a pressurized fluid delivery circuit, the displacement of the pump can be controlled by pressure in the fluid delivery circuit over a first pressure compensated range when work circuits connected thereto are capable of being operated within the first pressure range and also at a second higher pressure compensated range if any work circuit requires a higher pressure by using the pressure above a preselected value in the work circuit to change the range pressure compensation to a higher level through adjustment of control components.
