摘要： A method of controlling a hydraulic valve includes putting a first control chamber under pressure and putting a second control chamber to return so as to cause a slide to move into one of two end positions, putting a second control chamber under pressure and putting the first control chamber to return, thereby causing the slide to move into the other one of the two end positions. An intermediate step of applying pressure to the one of the first or second control chamber that was connected to return can be provided so that both control chambers are maintained simultaneously under pressure for a determined length of time.

摘要： A nozzle and a device for the application of the nozzle are disclosed. In the nozzle a mechanism is provided so that the dimensions of the hole for the flow of fluid can be varied according to the pressure differential between the inlet and the outlet. The above can be applied to the making of nozzles and/or devices, the delivery rate of which is directly proportionate to the differential pressure between the inlet and the outlet.

摘要： A hydraulic actuator containing a hollow body defining a cylindrical cavity and a rod which is mounted to slide within the body along a sliding axis between two end positions and which is integral with a piston sliding in a sealed manner within the cylindrical cavity in order to define two chambers. The rod defines an interior passage, connecting the two chambers, which has a valve comprising a shut-off member which is returned towards a seat and closes the passage. The rod receives a push member which can move relative to the rod between a position apart from the shut-off member and a position forcing the shut-off member to open. The push member is constrained, when the rod reaches the end of its stroke, by the push member engaging with a portion of the hollow body.
