| 092128000 | WITH ASSEMBLY OR DISASSEMBLY FACILITATING MEANS | 6 |
| 20100319529 | Valve Cap - There is disclosed a valve cap for sealing an aperture in a pump; a plugging assembly for use in a valve cap to provide a seal at an aperture in a pump; a docking unit for use with a plugging assembly for sealing an aperture in a pump; and a method of sealing an aperture in a pump. In an embodiment of the invention, a valve cap ( | 12-23-2010 |
| 20110247487 | LINEAR ACTUATOR - The present invention relates to a linear actuator. A slide table of the linear actuator includes a table main body and an end plate connected to another end of the table main body. On a base portion of the table main body, four workpiece retaining holes are formed, and fitting seats are disposed respectively about the workpiece retaining holes on radial outer sides thereof. The fitting seats are formed at the same time that the table main body is formed by press molding. | 10-13-2011 |
| 20120060685 | VARIABLE DISPLACEMENT RADIAL PISTON FLUID WORKING MACHINE - A variable displacement fluid working machine includes an inward ring and an outward ring, one of the inward ring and the outward ring including a rotatable ring cam coupled to a drive shaft, the other including a plurality of radially extending piston cylinders circumferentially spaced around the respective ring. The outward ring has first and second axially spaced structural members and a plurality of demountable blocks demountably retainable therebetween, the demountable blocks having either piston cylinders or ring cam segments. The demountable blocks are removable radially to facilitate maintenance and repair and to facilitate radial access to the inward ring. | 03-15-2012 |

| 20140202326 | MOUNTING ARRANGEMENT FOR A PISTON-CONNECTING ROD ASSEMBLY IN A REFRIGERATION COMPRESSOR - The arrangement is applied to a compressor which comprises: a crankcase, carrying a cylinder provided with a lateral slot and in which is housed a piston provided with two radial holes and with an eccentric axial hole; a connecting rod connected to a crankshaft driven by an electric motor and having a smaller eye mounted in the piston; and a wrist pin having a first end turned to the bearing hub of the crankcase, a second end turned to the lateral slot of the cylinder and a diametrical hole, adjacent to the second end in which is provided an engaging means, for the axial and rotational coupling of a tool for mounting and indexing the wrist pin, in the interior of the piston, in a position in which the diametrical hole is axially aligned with the eccentric axial hole, so as to allow an elastic pin to be introduced in said diametrical hole and in said eccentric axial hole. | 07-24-2014 |
| 20160186788 | SELF-ALIGNING MOUNTING AND RETENTION SYSTEM - A clamp is secured to a displacement pump, and the clamp includes an axial ring and a tightening ring. The axial ring is mounted above the tightening ring, and the axial ring is configured to align the displacement pump during mounting and to limit the stoke of a pump rod within the displacement pump. The tightening ring may be tightened such that the axial ring and the tightening ring exert a clamping force on a drive housing, which secures the displacement pump to the drive housing. The tightening ring may receive a projection extending from the drive housing to provide structural support to the drive housing. | 06-30-2016 |
