摘要： Before inner components of a hydraulic shock absorber (1), such as a cylinder (3), a piston (24) and a piston rod, are placed, an outer shell (2) is joined with a joint portion of an assembling apparatus so that a gas pressure chamber and the outer shell are in communication with each other. A low-pressure gas is supplied in the gas pressure chamber (14) and the outer shell. Under a pressure of the low-pressure chamber, an oil tank (10) subassembly is inserted in the outer shell and is fitted therein to form an oil tank. The oil tank is divided into an oil chamber (13) and a gas chamber by a diaphragm (12). By this assembling method, it is possible to supply the low-pressure gas into the gas chamber without a need for a gas-supplying hole for supplying the gas into the gas chamber.

摘要： The present specification relates to a telescopic hydro pneumatic suspension unit comprising a body member (10) connectible to one of the sprung and unsprung masses of a vehicle and provided with an internal hydraulic cylinder (12) wherein a piston (16) is reciprocable, a piston rod (18) connected to the piston (16) being connectible to the other of said masses. Flexible diaphragm means (40) co-operate with the body member (10) and said hydraulic cylinder (12), to define both a hydraulic chamber (48) and a pneumatics chamber (50). The end of the piston rod (18) within the hydraulic cylinder (12) is axially bored to act as a pump chamber (74), and engages over an axially apertured pump rod (72) secured axially in said cylinder (12), the pump chamber (74) communicating with a hydropneumatic cham ber (38) through suitably arranged valves (80,86; 108,110). Thus relative axial movement between the hydraulic piston rod (18) and the pump rod (72) is effective to transfer hydraulic fluid from the hydropneumatic chamber (38) to the hydraulic chamber (48) with consequent effect upon the axial position of the hydraulic piston rod (18) in its cylinder (12). However, such a construction has required accurate machin ing of various parts and the use of certain complex components.
The present invention provides a hydropneumatic suspen sion unit as described hereinabove, which avoids the necessity for the extremely accurate machining of certain parts, by the provision of a fluid flow passage in the form of a groove (96) in the outer surface of the pump rod (72). The groove (96) communicates with the pump chamber (74) in the piston rod (18) and co-operates with a pump rod seal (106) carried by the hydraulic piston (16) or its piston rod (18), to thus permit fluid transfer to the pump chamber (74) from the hydraulic cylinder (12) whenever the pump rod seal (106) is moved by the hydraulic piston (16) to a position wherein an end of said groove (95) is opened to the high pressure end (58) of the hydraulic cylinder (12). By the use of a seal (106) and groove (96), the unit is able to function as required without the necessity for accurately machined equivalent components.

摘要： The present specification relates to a telescopic hydro pneumatic suspension unit comprising a body member (10) connectible to one of the sprung or unsprung masses of a vehicle and provided with an internal hydraulic cylinder (12) wherein a piston (14) is reciprocable, a piston rod (16) connected to the piston (14) being connectible to the other of said masses. Flexible diaphragm means (36,38,D) co-operate with the body member (10) and said hydraulic cylinder (12) to define hydraulic chamber (40,44) respectively in com munication with the hydraulic cylinder spaces (52,54) in front of and behind said piston (14), and a pneumatic chamber (42,46) contiguous with each hydraulic chamber (40,44). The end of the piston rod (16) within the hydraulic cylinder (12) is axially bored to act as a pump chamber (62) which engages over an axially apertured pump rod (64) which is axially secured within the cylinder (12), and which communicates with said hydraulic chambers (40,44) through suitably arranged pump inlet (&2) and delivery valves (68,70). Thus relative axial movement between the hydraulic piston rod (16) and the pump rod (64) is effective to transfer fluid from one hydraulic chamber (40,44) to another, with consequent effect upon the axial position of the hydraulic piston (14) in its cylinder (12). With known suspension units of this type accurate machining of virtually all of the respective pump parts, is required and certain complex components are used, the construction being therefore expensive to manufacture.
The present invention seeks to overcome the above disadvantages by avoiding unnecessary and unnecessarily complex components and by eliminating close manufactur ing tolerances in some major components. The present invention provides a fluid flow passage in the form of a groove (80) in the outer surface of the pump rod (64). The groove (80) communicates with the pump chamber (62) in the hydraulic piston rod (16) and co-operates at one end with a pump rod seal (76) carried by the hydraulic piston (14) or its piston rod (16), to permit fluid transfer to the pump chamber (62) from the high pressure end (52) of the hydraulic cylinder in front of the hydraulic piston (14) whenever said pump rod seal (76) is moved by the hydraulic piston (14) to a position wherein said end of groove (80) is opened to said high pressure end (52) of the hydraulic cylinder (12). Co-operation between the groove (80) and the pump rod seal (76) provides a very simple and reliable means of sensing or detecting the axial position of the piston (14) within cylinder (12) and of maintaining the piston (14) substantially in that position by balancing the rates of fluid flow to and from the high pressure end (52) of the cylinder (12).
