摘要： Disclosed are seal arrangements in a hydraulic device. The seal arrangement includes a seal channel defining a loop. A seal is seated within the seal channel. A coolant flow passage has a first part intersecting with the seal channel at a first point and a second part intersecting with the seal channel at a second point. The first part of the coolant flow passage is configured to provide hydraulic fluid to the seal channel such that, at the first point, a first portion of the hydraulic fluid flows in a first direction around the loop and a second portion of the hydraulic fluid flows in a second direction opposite to the first direction around the loop. At the second point, the first portion of hydraulic fluid and the second portion of hydraulic fluid are configured to flow into the second part of the coolant flow passage.

摘要： A cylinder apparatus includes a piston and a cylinder tube including a first end and a second end. The cylinder tube is formed to include a central bore extending from the first end to the second end for receiving the piston therein and a second bore extending from the first end to the second end spaced apart from the central bore. The cylinder apparatus also includes a first end cap coupled to the first end of the tube and a second end cap coupled to the second end of the tube. The second end cap is formed to include a first port in communication with the central bore of the tube and a second port in communication with the second bore. First end cap and second end cap have similar configurations and use substantially identical seals. Therefore, the semi-finished parts of the present invention have substantially identical configurations, regardless of the specific embodiment selected for a particular use. Ports and fittings can be selectively added either to the semi-finished first end cap or to the semi-finished second end cap to customize each finished cylinder for use in a particular environment.

摘要： A linear telescopic actuator (1) that comprises a cylinder (2), a sliding part (3), a spring seat (4) and a first compression spring (5) capable of resiliently opposing the sliding part (3) approaching the spring seat (4). The spring seat (4) presents an outer annular groove (6) and the cylinder (2) includes an inner annular groove (7). The actuator (1) also presents a blocking part (8), the actuator (1) being adapted to adopt selectively an assembled configuration and a disassembled configuration. The blocking part (8) in the assembled configuration is engaged inside the inner and outer annular grooves (6, 7). The blocking part (8) in the disassembled configuration being disengaged from one of the grooves so as to allow spring seat (4) to slide in the cylinder (2).

摘要： A double-effect hydraulic actuating cylinder, particularly for hydraulic steering devices and for marine outboard motors, includes a cylinder slidably fitted on a coaxial rod, or vice versa, which sealingly projects out a head of the cylinder and carries a separating piston dividing the cylinder into two variable volume chambers, each connected to one of two inlets/outlets of the pump and a sealing head for the mutual sliding of cylinder and rod. The rod is non-slidably connected to a bracket fastening the cylinder to the motor, and an idler arm is secured to the motor and integral with the cylinder. At least one of the sealing heads include a sealing element engaging the inner side walls of one of the two variable-volume chambers, and a separate, coaxial plug element placed at the end parts of the cylinder and preventing the sealing element from sliding.
