20060191406 - Cylinder rod with position sensor surface markings: A cylinder rod with wear-resistant surface markings is provided. The cylinder rod may include a rod substrate, a thermal-spray coating disposed on a surface of the substrate, and one or more surface markings disposed on the coating at predetermined locations along the length of the cylinder rod....

20060191407 - Composite brake cylinder: A composite material and framework structure adapted to be utilized as a piston and cylinder apparatus. A cylindrical tube composed of a composite material is compressed between two end caps at the axial ends of the cylindrical composite tube. Beam elements extend between the end caps and maintain the compression...

20060180015 - Piston mechanism provided with divergent pistons: A piston mechanism comprises a crankcase (4), a crankshaft (7) with three crankpins (48, 50, 51), a cylinder (1) with diverging pistons (5, 6) defining working chambers (10, 11, 12, 13) having inlet (14) and outlet (15) openings, and two connecting members (27, 28), one of which cooperates with the...

20060180016 - Axial piston machine with offset positioning element and cam disk for such an axial piston machine: The invention relates to an axial piston machine (1) comprising a housing (2) in which a drive disk (7) and a cylinder block (12) axially disposed next to it are received so as to be rotatable relative to each other about longitudinal center axes (11, 13). These axes run obliquely...

20060180017 - Stop for a slide assembly: A rodless slide assembly is provided illustratively having a longitudinally-extending cylinder, a carriage, a stop assembly, and a catch assembly. The longitudinally-extending cylinder comprises first and second ends and a path of travel extending therebetween. The carriage is slidable on the path of travel on the cylinder between the first...

20060180019 - Piston balancing system: A piston pump or compressor has a dynamically balanced drive assembly in which nearly all of the rotational, oscillatory and axial forces on the rotating drive shaft are canceled. The piston is primarily balanced by adding an oscillating counter weight mounted to the connecting rod to convert oscillatory forces into...

20060180018 - Reciprocating compressor frame: A reciprocating compressor barrel frame comprising a continuous curved wall having an inner surface and an outer surface. A housing is formed by the inner surface of the curved wall. A pair cross head shoe supports extend from the outer surface of said curved wall in opposite directions perpendicular to...

20060180020 - Piston rod retention system: A connector assembly comprising a housing and a tensile member disposed within the housing. The tensile member comprises first and second end portions. Each end portion sealingly engages the housing to form a hydraulic chamber therebetween. A first connector pivotally coupled to the first end portion. The axial position of...

20060174760 - Swing cylinder: A swing cylinder having a body and an end cap on each end of the body. The cylinder also has a piston arranged within the body. The cylinder has a rod engaged with the piston and has an arm attached to one end thereof. A guide is arranged on the...

20060174761 - Compressible fluid pressure actuator: An inner space connected to a power source and an inner space connected by way of a pressure loss part with respect to the flow of compressible fluid are provided, thereby obtaining effects similar to when the volume occupied by the compressible fluid with respect to the entire inner space...
