092146000 | PLURAL UNITARILY MOUNTED CYLINDERS OR FRAME THEREFOR (161) | 10 |
20110126700 | Undercarriage for a telescopic frame - A telescopic undercarriage for raising and lowering a frame. The undercarriage includes a base section having a pair of parallel base legs extending from a first end to a second end of the base section, the base section including a first plurality of braces extending between respective upper surfaces of the base legs and a second plurality of braces extending between respective lower surfaces of the base legs, the base legs, first plurality of braces and second plurality of braces collectively providing an elongate central base section passage. The undercarriage also includes an extendable section slidably disposed within the base section passage and having opposed legs, a drive system for extending and retracting the extendable section relative to the base section. | 06-02-2011 |
20120067202 | Reciprocating Compressor Wrist Pin Bearing and Lubrication Passageway - A compressor, as well as a lightweight and strong casting for a compressor, are disclosed. The compressor, which may be a reciprocating compressor for use in compressing high-pressure refrigerants such as CO | 03-22-2012 |
20120325081 | HIGH POWER HYDRAULIC CYLINDER - A hydraulic device that includes a case, and a substantially hollow rod slidably extending from the case. The rod has a ram on a first end thereof that caps the rod to form a first hydraulic piston. The rod has a second hydraulic piston on a second end thereof, inside the case. The first and second pistons are at least partially radially coextensive, and a pressure barrier inhibits high pressure on the first piston inside the hollow rod from reaching a side of the second piston that faces the first piston. | 12-27-2012 |

092147000 | With casing or support for rotary shaft | 4 |
20090126562 | COMBINED PISTON-EXPANDER COMPRESSOR - The invention concerns a combined piston-expander compressor comprising a plurality of pistons ( | 05-21-2009 |
20110138996 | AXIAL PISTON MACHINE - An axial piston machine of an inclined axis design includes a housing in which a cylinder drum is disposed. The cylinder drum is rotatably supported on a central journal which is hingedly connected to a drive shaft. The central journal is inserted, in an axially displaceable manner, in a central journal bore formed in the cylinder drum which extends approximately coaxially to the longitudinal axis of the cylinder drum. A compression spring is disposed in central journal bore which bears against an end face facing away from the drive shaft, and loads the cylinder drum against a control disk. A radial groove is formed in central journal, in which an O-ring is accommodated, by way of which the central journal is held in a non-positive manner in the central journal bore when the axial piston machine is assembled and disassembled. | 06-16-2011 |
20120297972 | Subassembly Forming A Hydrobase For Hydraulic Motors, And Assembly Method - The present invention relates to a subassembly for forming a hydraulic motor after assembly onto an assembly including a shaft, said subassembly including a cover forming a housing element, a multilobe cam, a cylinder block opposite the cam, pistons guided so as to slide radially within the respective cylinders of the cylinder block and bearing on the lobes of the cam, and a valve intended to apply pressurized fluid to said pistons in series, wherein said subassembly includes means for temporarily attaching the cylinder block to the cover and means for accessing an element of the valve through the cover in order to enable, during installation, the angular positioning of said element with respect to the shaft, followed by the attachment thereof to the shaft. The present invention also relates to a method for assembling such a hydrobase. | 11-29-2012 |
092149000 | V-type | 1 |
20090007775 | Engine for Aeronautical Applications II - An improved engine for aeronautical applications includes a forged cylinder block having a drive device rotatably mounted therewithin and a motive device for rotating the drive device, the motive device including two cylinder banks in a V-type configuration and a plurality of cylinders mounted within the cylinder banks for producing power and rotating the drive device. The forged cylinder block further includes a plurality of cylinder cavities formed in the cylinder banks and the upper approximately one-third of each of the cylinder cavities is generally surrounded by a generally toroidal cooling chamber, and the lower approximately two-thirds of each of the cylinder cavities is generally free of any surrounding cooling chambers. Finally, a coolant circulation device in fluid transmission connection with each of the cooling chambers is operative to circulate cooling fluid therethrough whereby the upper approximately one-third of each of the cylinder cavities is cooled by the cooling fluid. | 01-08-2009 |
