摘要： A tank for a hydraulic fluid has a housing with opposed end walls and side walls defining an interior chamber. A primary baffle is disposed inside the housing and divides the interior chamber into an inlet chamber and an outlet chamber, with a primary gap between the primary baffle and the housing fluidly communicating between the inlet chamber and the outlet chamber. The primary baffle further defines a contact surface facing the inlet chamber and has first and second weirs which extend into the inlet chamber. A first fluid inlet fluidly communicates with the inlet chamber and is oriented along a first inlet axis that intersects the contact surface, while a fluid outlet communicates with the outlet chamber. The tank produces an interior flow that mixes and deaerates the fluid as it travels from the first fluid inlet to the fluid outlet.

摘要： A hydraulic actuator comprising a hollow body (1, 3) defining a cylindrical cavity and a rod (5) 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 (C1, C2). The rod defines an interior passage, connecting the two chambers, which has a valve (20) comprising a shut-off member (21) which is returned towards a seat (22) and closes the passage. The rod receives a push member (15, 26) which can move relative to the rod between a position apart from the shut-off member (21) 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 (3) of the hollow body.

摘要： A fluid tank includes a tank main body that contains a fluid and a bubble removing device that is provided inside the main body and removes bubbles in the fluid. The main body includes a partition and a delivery port through which the fluid is fed to outside. The bubble removing device has an outflow port through which the fluid from which the bubbles have been removed flows to the inside of the main body and a bubble exhaust port through which the bubbles which have been removed are discharged to the inside of the main body. The delivery port is provided adjacent to the outflow port relative to the partition. The partition partitions the inside of the main body into a side in which the outflow port and the delivery port are provided and a side of the bubble exhaust port.

摘要： A hydraulic system for synchronized movement of multiple cylinders in a horizontal plane includes a bidirectional pump, a shuttle valve cross-connected between pump outlets, flow-control check valves, and control valves which combine to reduce the number of valves in the hydraulic circuit and to reduce total cost of components for the system. The shuttle valve of the hydraulic system provides fluid for resynchronizing extension and retraction of multiple cylinder assemblies without disconnection of lines, provides air removal without disconnection of lines, allows easy addition/refill of hydraulic fluid, and allows excellent control of the extendable cylinder assemblies.

摘要： A valve has a valve body with first and second intake passages, first and second supply passages and a reservoir return passage defined therein. A shuttle member is movable within the valve body between a first flow position and a second flow position. In the first flow position, the shuttle member defines a first fluid flow path between the first intake passage and the first supply passage and a second fluid flow path between the second supply passage and the reservoir return passage. In the second flow position, the shuttle member defines a third fluid flow path between the second intake passage and the second supply passage and a fourth fluid flow path between the first supply passage and the reservoir return passage. The valve is useful in a bi-directional hydraulic power system having at least one hydraulic component, a reservoir for hydraulic fluid, and a bi-directional pump.

摘要： A hydraulic apparatus such as a bleeder screw comprises an inner end, an outer end, and a main body extending between the inner end and the outer end. The main body includes a first section having a threaded outer peripheral surface a second section disposed between the first section and the inner end. The second section has a smaller diameter than the threaded outer peripheral surface of the first section, and an axial length of the threaded outer peripheral surface is less than an axial length of the second section. An internal fluid passage opens through an outer peripheral surface of the second section at a location between the inner end and the threaded outer peripheral surface, and the internal fluid passage opens through the main body at a location between the threaded outer peripheral surface and the outer end. Another hydraulic apparatus comprises a first fluid reservoir having a first reservoir chamber and a first reservoir outlet; a second reservoir having a second reservoir chamber and a second reservoir outlet; and a common fluid passage in fluid communication with the first reservoir outlet and the second reservoir outlet to flow fluid from both the first reservoir chamber and the second reservoir chamber to the atmosphere.
