Abstract: A cartridge of a water supply valve that controls the flow rate and temperature of water without causing interference between flow rate control operation and temperature control operation of the valve. In the cartridge, a flow rate control knob (12) angularly moves forwards and rearwards and actuates a control lever (14) to open or close cold and hot water supply holes (1a and 1b). A temperature control knob (13) is coupled to the flow rate control knob (12), linearly moves leftwards and rightwards, and actuates the control lever (14) to control the opening ratios of the water supply holes. Thus, this cartridge does not change the existing temperature of water during flow rate control operation or change the existing flow rate of water during temperature control operation. This invention reduces the quantity of water to be unnecessarily wasted and, at the same time, prevents undesirable consumption of excessive energy.

In response to the position of the handle, each valve connects a separate chamber alternately to either the supply passage or the tank passage and different pressure sensor produces an electrical signal indicating a level of pressure in the chamber of each valve. Thus an electrical signal is produced from each valve to indicate motion of the handle.

Abstract: A joystick controller is provided in a hydraulic circuit having a pair of hydraulic actuators and oriented with respect to the operator so that movement of a control lever of the joystick controller relative to a reference axis oriented perpendicular to the operator results in control signals being generated and delivered to the first and second main control valves so that the respective cylinders are moved in a direction that is intuitive to the operator. For example, forward movement of the control lever results in both hydraulic actuators moving in the same forward or downward direction and movement of the control lever rearwardly results in both actuators moving in the rearward or upward direction. Likewise, movement of the control lever along an axis that is oriented forty five degrees from the reference axis results in control of one of the actuators independent of the other one.

Abstract: It is designed that an oil pressure signal can be output by operating an operation lever in a twisting direction; a structure can be made simple and its assembly and adjustment are easy; an operation force can be reduced; and a layout is not restricted. It is also designed that when the operation lever is left free after it is twisted, it returns smoothly to the original neutral position. When the operation lever is twisted about the lever axis, the shaft supported by bearings is twisted. The twist of the shaft is converted into the movement in a direction to move the pistons by first and second levers, and the pistons are moved. When the pistons are moved, the oil pressure signal is output from the discharge ports. A disk plate is separated into a first disk plate to which the root of the operation lever is attached and a second disk plate which is tiltably supported by a tilting fulcrum.

Additionally, a precision edge is defined within each of the orificing devices to control the flow of pressurized hydraulic fluid through the respective orificing device and maintain a consistent viscous drag therethrough independent of temperature and oil-viscosity variations.

A motion alarm actuator is connected to the control body and is associated with a normally closed switch so that in a centered position of the control body the normally closed switch is held open, but when the control body moves to any one of its positions actuating a pilot valve, the switch, which forms an alarm switch, moves to its normally closed position.

Abstract: A drive linkage that is used for controlling valves for the drive motors of an implement or machine, such as an excavator, has a pair of links that can be loaded in tension and compression by manually moving operating levers. The links in turn actuate a cam that tilts a swiveling disk to operate a pilot valve assembly normally used for a joystick control. The links are connected so that the pilot valve can selectively operate motors for driving opposite tracks on sides of the implement in either forward and reverse direction, and wherein motors for both sides can be operated in a forward direction and in a rearward direction. Additionally, each of the drive motors can be controlled so the motor for one side drives in forward direction and simultaneously the motor for the other side drives in reverse direction. A control disk for moving the plungers is operated through a cam plate that is in turn moved by moving the links.
