Abstract: A valve device (1) comprising; a body portion (2) having a plurality of openings, a valve seat (6) located within said body portion (2), an end stop (4,8), corresponding to an opening of said body portion (2), said end stop (4,8) comprising a port portion (38,39) through which fluid may flow, and a nozzle (33,35), in fluid communication with said port portion (38,39), said nozzle (33,35) configured for sealing against said valve seat (6) and thereby preventing flow through the valve device (1), the valve device (1) being openable by relative motion of said nozzle (33,35) with respect to said valve seat (6), and adjustment means configured to allow independent adjustment of the location of said nozzle (33,35) with respect to said valve seat (6).

Abstract: A hoisting apparatus comprising a frame (2), a rope drum (3) provided with a groove (12), a hoisting motor (4), a gear (5) and a pinion (6). The hoisting motor (4) is at least partly positioned inside the rope drum (3) supported against the frame (2) by its both ends. The hoisting motor (4) and the gear (5) are supported against the frame (2) only by one end of the rope drum (3), by which end the hoisting motor (4) and the gear (5) are arranged to rotate the rope drum (3) via the pinion (6). The pinion (6) is positioned between a cylinder, which is parallel to the longitudinal axis of the rope drum (3) and defined by the housing (15) of the hoisting motor (4), and the rope drum (3).

Abstract: A winch having a main frame on which a drum is rotatably mounted and which is unidirectionally driven by a drive shaft rotatably mounted in the frame, the drive shaft having a pair of axial gear rings rotatably mounted thereon and engageable in unidirectional driving engagement with the shaft, the gear rings meshing with the diametrically opposed pair of gear sectors which are oscillated by foot pedals attached thereto so that oscillatory motion of the gear sector results in unidirectional rotation of the drum.
