摘要： PROBLEM TO BE SOLVED: To prevent an increase in a pressure and cavitation, in the load reaction force type fluid controller of a steering system using an unequal area cylinder. SOLUTION: A fluid controller 15 is load reaction force type to control a flow of fluid to a non-uniform area steering cylinder 25. The controller 15 contains a valve structure 27 forming a load reaction fluid passage LR to allow a flow of fluid between control fluid ports 21 and 23 through a fluid meter 29 in response to an external load exerted on the cylinder 25 in a neutral position. The valve structure 27 contains fluid passages 97 and 99 to interconnect the load reaction force fluid passage LR and a return port 19 when it is in a neutral position. When a rod end chamber A is contracted, fluid is introduced from the return port 19 to the load reaction force fluid passage LR, cavitation is prevented from occurring. Further, when a head end chamber B is contracted, fluid flows from the load reaction force fluid port LR to the return port 19 to prevent an increase in a pressure.

摘要： PURPOSE:To reduce the size and perform accurate detection of a pressure by locating a first orifice between a first radial through-hole and an axial slit and a second orifice between a second radial through-hole and an axial groove. CONSTITUTION:An axial slit 62 communicated with a first radial through-hole 61-1 is formed in a spool 21. A pressure detecting port 64 through which the first and second annual grooves of a sleeve 22 are communicated with the outside and a drain port 66 are formed in a housing. A first orifice 70 is formed between the first radial through-hole 61-1, a third radial through-hole and the axial slit 62 and a second orifice 71 is formed between a second radial through- hole 61-2 and an axial groove 48. Further, a controller 82 is arranged between a pressure detector 80 and a drive motor 81 for an oil pressure source 8 comprising a variable pump, and only when a handle is turned, a delivery amount of a variable pump 8 is increased.

摘要： PURPOSE: To reduce lateral jerk of a connected type vehicle without using a cushion valve or an accumulator for a steering system. CONSTITUTION: A fluid controller 11 for controlling the flow of a fluid from a fluid source 73 to a steering cylinder 77 comprises a fluid meter 17 and valve mechanism including a spool 33 and a sleeve 35. A housing and the valve mechanism define a main fluid path 113 including a main variable flow control orifice Al and the fluid meter 17 in series flow relation between an inlet port 23 and a first control fluid port. The main variable flow control orifice Al is formed by fluid communication between first fluid passages 94R, 123L provided at the spool 33, and first fluid port means 101R, 131R provided at the sleeve 35. When the spool 33 rotates relative to the sleeve 35 from a neutral position to a first operating position, continuous fluid communication is provided between the inlet port 23 and the first fluid passage of the spool 33, and the rotational displacement between the spool 33 and sleeve 35 becomes considerably large to reduce the incidence of lateral jerk.

摘要： PURPOSE:Not to generate large torque at steering and to dispense with a large space by connecting the column of a handle to the input shaft of a hydraulic actuation device, and connecting a pair of controlling ports to a front wheel steering cylinder. CONSTITUTION:An inlet port 7, an output port 8, and a pair of controlling ports are provided in a housing 6, and a changeover valve 9 is rotatably arranged in a center hole. A measuring part 19 is provided with an internal gear member 21 and an external gear member 22 which is eccentrically provided in the internal gear member 21 and autorotation and revolution are performed, and the spline 23 of the external gear member 22 is engaged with the spline of a first drive shaft 17. On the inside of an output shaft 24, a spline 26 is provided, and a second drive shaft 27 engaged with the splines 23,26 is provided. Because the output shaft 24 is connected to the external gear member 22 of the measuring part through the second drive shaft 27, autorotation of the external gear member 22 is picked up with the output shaft 24, and rotation of the output shaft 24 is transmitted to a front wheel steering device through a connecting member 4.

摘要： PURPOSE:To easily conduct manual steering operation in case of stoppage of discharge oil from a hydraulic source by interposing a check valve in a hydraulic line which branches off from the discharge line of a pump and leads to the auxiliary input port of the directional control valve of a steering unit. CONSTITUTION:A steering unit 2, which has a directional control valve 7 operated by an handle 1, and a steering cylinder 5 are connected to communicate with each other by the first hydraulic lines 3 and 4, and the delivery side of a pump 6 is connected to the steering unit 2 through the second hydraulic line 2 in which a pressure and flow compensating valve 10 is installed. The directional control valve 7 has input and output ports 34 and 35, the first and second auxiliary input ports 38 and 39, a pilot port 40, and left and right ports 43 and 44, and the third and fourth hydraulic lines 103 and 104, which have branched off from the second hydraulic line 8 and in which solenoid valves 105 and 106 are installed, are connected with the auxiliary input ports 38 and 39, respectively. In this case, check valves 108 and 109 are installed further in the third and fourth hydraulic lines 103 and 104.
