Abstract: A cylinder is interposed between a machine frame and each of outriggers, which are vertically swingably disposed at opposite sides of the machine frame, so as to lift up and down the outrigger. Fluid passages are formed in a rod part of the hydraulic cylinder. Connection portions of fluid suction and delivery ports of the respective fluid passages to be connected to the respective hydraulic pressure hoses are disposed adjacent to a pivot of the hydraulic cylinder.

Abstract: Hydraulic motor with propulsion members (10) positioned between a cam (3) associated with a shaft (2) and a reaction element (1b), said propulsion members (10) consisting of two elements (11,12), i.e. an internal element (12) and external element (11), telescopically slidable with respect to each other in a radial direction and respectively provided with annular bearing edges (11a,12a) kept pressed against corresponding contact surfaces (3a, 1a) of said cam (3) and said reaction element (1b) via respective resilient means (16), the resilient means associated with the external element (11) of the propulsion member being arranged outside the said element, characterized in that the resilient means (16) associated with the internal element (12) are arranged inside the propulsion member (10) and positioned in the radial direction between said internal element (12) and associated means (52,55) for mechanically retaining them.

Abstract: A fluid cylinder with a swivel joint which is more improved with high utility is provided. To this end, in the fluid cylinder, a flow passage (R2b) leading to a chamber (1F) at the rod side of the cylinder is provided inside a rod (3), and a pin hole (3H) in a rod front end portion (3F) and a pin (P1) fitted in the pin hole (3H) are formed into a swivel joint so that the flow passage (R2b) is always guided to an outside even if the pin hole (3H) and the pin (P1) are relatively rotated.

Abstract: An improved double wall cylinder includes a neck which extends along an axis generally coincident with the longitudinal axis of the cylinder. This neck supports an outer wall and an inner wall and includes a first passage and a second passage for providing fluid communication between the cylinder and a remote control unit. The outer and inner tubular walls are preferably formed of commonly available tubing and the manufactured cost of the cylinder may be reduced by the fact that one of the tubular walls is devoid of threads, apertures and other machined portions. If the end gland is removed for service, the inner wall is frictionally retained in position while the piston assembly is withdrawn. The inner wall may then be removed, leaving the outer wall attached to the neck by a threaded connection. Risk of accidential loss of parts is thereby reduced. The cylinder is configured for use with a mounting plate of the type having a pair of spaced, outwardly extending hollow lugs.

Abstract: A plurality of piston heads (14, 16, 18) are spaced apart along the length of a single piston rod (12). A travelling cylinder body (20, 22, 24) is associated with each piston head (14, 16, 18). The traveling cylinder bodies (20, 22, 24) and the piston heads (14, 16, 18) define a first fluid chamber (92, 100, 88) on a common first side of the piston heads (14, 16, 18) and a set of second fluid chambers (96, 104, 90) on a common opposite side of the piston heads (14, 16, 18). A separate fluid supply and return tube (94, 102, 82) is provided for each first fluid chamber (92, 100, 88). The tubes (94, 102, 82) extend through the hollow interior (42) of the piston rod (12). A space exists in the hollow interior (42) between and around the tubes (94, 102, 82). This space serves as a supply and return passageway for all three second fluid chamber (96, 104, 90). Passageways (98, 106, 80) extend from interior space (42) to each of the second fluid chambers (96, 104, 90).

Abstract: A pump is described including an elongated cylindrical reservoir, a valve casing, at which the pump is pivotally fixed in space, and a pump chamber which are in a linear arrangement. A piston within the pump chamber is connected to a link, the end of which is pivotally fixed in space. A handle atop the reservoir is used to pump fluid from the reservoir to an attached device to be operated. Bores and check valves within the valve casing regulate the flow of fluid through the pump. A release mechanism which allows fluid to flow from the attached device to be operated back into the reservoir is activated by rotating the handle.

Abstract: A fluid operated cylinder is provided including a tube having rod end and blind end caps which are attached to the tube by radial plugs. The plugs permit relative movement between the rod end cap and the tube when the cylinder is operated to accommodate axial misalignment between the piston rod and the tube.

Abstract: A pair of sleeves are fixedly mounted in axial alignment on opposite sides of the power plant enclosure of a bulldozer. Rotatably received in each sleeve is a trunnion having at its outer end a yoke holding one of the blade lift cylinders of the bulldozer. The pair of opposed fluid chambers in each lift cylinder are in communication with a pressurized fluid source and drain via passages formed in the respective trunnion and sleeve. For holding the trunnions in position in the respective sleeves against the axial thrust which may be applied thereto in both directions, a stop disc is bolted to the inner end of each trunnion for engagement with one of the sleeves and with a cover bolted to the inner end of each sleeve.

Abstract: The present invention comprises a fluid pump motor unit and a controller unit which controls the output of the pump/motor irrespective of the speed of the power source driving the pump/motor unit.The pump/motor unit comprises a cylindrical housing within which there is arranged at least one rectangular expansible cylinder assembly mounted on a crankshaft in a radial pattern, the cylindrical assembly being pivotally mounted within the housing for movement about trunnions, the rectangularly adapted piston assembly within said housing being journaled on a crankshaft which crankshaft with respect to the centerline of the cylindrical housing has a rotation parallel to, but spaced from, the centerline of the housing. The pivotal oscillation of each cylinder assembly alternately opens a port for the inflow of a fluid and subsequently closes that port while simultaneously opening another port for the outward flow of the fluid under compression as the piston moves toward the top of the chambers.

Abstract: A pair of side-by-side hydraulic fluid supply and return hoses are connected to side-by-side end ports at the free end of a journal block which is located between two spaced apart bearing blocks. A pair of coaxial, oppositely projecting, tubular journals carried by the journal block, and rotationally received in coaxial blind socket portions of passageways formed in the bearing blocks, serve to mount the journal block and hoses connected thereto for pivotal movement relative to the bearing blocks. Passageways in the journal block communicate the side-by-side hose ports with the interiors of the tubular journals which in turn communicate with the passageways in the bearing blocks via the blind sockets. The bearing blocks are detachably mounted onto an upper rear frame portion of a hydraulic tool, such as a hydraulic breaker. The bearing block passageways have ports on corresponding mounting sides of the bearing blocks which communicate with inlet and outlet ports in the tool housing.
