092109000 | PISTON WITH RIGID AXIALLY EXTENDING HOLLOW STEM | 8 |
20100050860 | Single-Acting Pneumatic Cylinder for Use on a Locomotive Platform - The pneumatic cylinder includes a cylinder body, a non-pressure head, a hollow piston rod, a piston head, and a push rod. The cylinder body has a mounting flange and an inlet port. The non-pressure head has a mounting flange. The hollow piston rod has an open end and a closed end. The piston head is secured to the hollow piston rod and defines the closed end of the hollow piston rod. The push rod has a socket end inserted within the hollow piston rod and a coupler end. The non-pressure head has a hollow rod guide bearing and a hollow rod seal and the piston head has a piston guide bearing and a piston seal. The hollow rod guide bearing and the hollow rod seal each slidably engage the hollow piston rod. The piston guide bearing and the piston seal each slidably engage the cylinder body. | 03-04-2010 |
20120180651 | Transmission System and Method of Repair - A transmission system and method of repair having a transmission servo rod received within a transmission housing bore, the rod having an aperture disposed along an exterior surface of the rod, configured to receive transmission fluid from a port within the transmission housing bore, a first recessed groove in the exterior surface of the rod disposed above the aperture; a second recessed groove in the exterior surface of the rod disposed below the aperture; and a first and second resilient sealing member received within the first and second recessed grooves, respectively, the resilient sealing members configured to engage an inner surface of the transmission housing bore. | 07-19-2012 |
20130213215 | CYLINDER - A cylinder includes a cylinder body assembly, a cylinder rod assembly, and a piston assembly. The cylinder body assembly includes a cylinder body. The cylinder body defines a receiving chamber. The cylinder rod assembly includes a rod fixed with the cylinder body. The rod includes an inclined resisting surface. The piston assembly includes a piston, a piston rod, and one or more resisting member. The piston is slidably received in the receiving chamber and sleeved on the rod. The piston rod protrudes from the piston and extending out from the receiving chamber. The piston rod is sleeved on the rod, and defines a through hole. The resisting member is movably mounted in the through hole. The piston and the piston rod slide relative to the rod, which enable the resisting surface to resist the resisting member to be partially exposed from the through hole. | 08-22-2013 |
20140130662 | PISTON ROD CLAMPING SYSTEM - A system, in certain embodiments, includes a piston clamping system including a piston rod comprising a piston rod shoulder and a piston rod nut coupled to the piston rod, wherein the piston rod nut and the piston rod shoulder are configured to axially capture first and second body portions of a piston therebetween. | 05-15-2014 |
20140230645 | GAS CYLINDER, IN PARTICULAR HIGH-PRESSURE GAS CYLINDER - The invention relates to a gas cylinder, in particular a high-pressure gas cylinder, the cylinder tube ( | 08-21-2014 |
092110000 | Hollow stem forms axially extending fluid passage | 2 |
20100186583 | Hollow double rod cylinder actuator - A double hollow rod cylinder is provided. The cylinder includes a cylinder body and a piston apparatus. | 07-29-2010 |
20130133512 | HYBRID CYLINDER - The invention relates to a hybrid working cylinder ( | 05-30-2013 |
092113000 | Relatively movable elongated part within stem | 1 |
20120097023 | Load Cylinder For Compensating Unbalanced Forces - A load cylinder for compensating unbalanced forces applied by a load. According to one implementation the load cylinder comprises a hollow ring-shaped body, a base fixed to a first end of the ring-shaped body, and a rod housed partially in the hollow space of the ring-shaped body, a chamber being delimited between side walls of the ring-shaped body, the rod and the base. The rod is housed partially in the chamber and may move in its interior. The rod comprises a housing on one end, and the load cylinder comprises a compensation member housed in the housing, the compensation member being acted on to cause the movement of the rod. The housing comprises a greater width than the width of the compensation member, with the result that the compensation member may move inside the housing. | 04-26-2012 |
