摘要： A method of using a sensor comprising the steps of: sensing a condition; transmitting a binary signal having either a first state or a second state indicative of the sensed condition; determining either a first or a second mode of operation of a prime mover to be in effect; operating the prime mover, in the first mode of operation, responsive to the first or second state of the binary signal; and operating the prime mover, in the second mode of operation, responsive to the rate of transition of the binary signal between the first and second states.

摘要： A control valve is used for a cooling apparatus having a compressor including a displacement variation mechanism and an external refrigerant circuit (30) connected to the compressor to form a cooling circuit. The discharge displacement of the compressor is regulated by controlling a control pressure, which acts on the displacement control mechanism. The control valve has a housing and an internal passage. The internal passage includes a valve chamber defined in the housing. A valve body is located in the valve chamber and controls the opening degree of the internal passage. A first pressure sensing structure senses the differential pressure between two pressure monitoring points (P1,P2) in the cooling circuit, that is, a primary pressure (22), and transmits a force corresponding to the primary pressure to the valve body. A second pressure sensing structure senses a secondary pressure, which is different from the primary pressure, and applies the secondary pressure to the valve body (43). The valve body (43) is positioned in the valve chamber (46) by a combination of forces corresponding to the primary pressure (PdH-PdL) and the secondary pressure (PdL-Pc), and the opening degree of the internal passage is controlled accordingly.

摘要： A displacement controlling device for a variable displacement type hydraulic pump comprising a cylinder (21) for varying the displacement of a variable displacement type hydraulic pump (2), a control valve (26) for controlling the supply and discharge of discharging pressure of the variable displacement type hydraulic pump to and from the cylinder, a fixed displacement type hydraulic pump (3) driven together with the variable displacement type hydraulic pump by the same engine (1), and a throttle valve (18) provided along a discharge line of the fixed displacement type hydraulic pump, wherein the control valve is changed over by virtue of comparison between a differential pressure between the discharge pressure and a loading pressure and a set differential pressure, which is a differential pressure across the throttle valve so as to control the displacement of the variable displacement type hydraulic pump via the cylinder, whereby the differential pressure is made to be a certain value that matches the set differential pressure.

摘要： A power steering apparatus having a fluid source for discharging pressurized fluid, a power cylinder, a control valve responsive to operation of a steering wheel for supplying the power cylinder with pressurized fluid from the fluid source, and a reservoir. The control valve has a first control portion for controlling the flow of pressurized fluid from the fluid source to the reservoir, and a second control portion for controlling the flow of pressurized fluid to the power cylinder. The first control portion has two paths connecting the fluid source and the reservoir, each of the paths being formed with at least one variable orifice of a center-open type which opens when the control valve is in a neutral state. The second control portion has two supply paths communicating with the fluid source and a pair of chambers of the power cylinder, each of the supply paths being formed with a variable orifice of a center-close type which closes when the control valve is in the neutral state, and two drain paths communicating with the pair of chambers and the reservoir, each of the drain paths being formed with a variable orifice of a center-open type which opens when the control valve is in the neutral state.
