Air pressure source for full air brakes or air-over-hydraulic brake systems. Single cylinder, inline two-cylinder (L2) and V two-cylinder (V2), providing a range of capacities for middle and heavy duty trucks.
The two-stage air compressor generates higher pressure by compressing air in two stages. Its characteristic is lower driven torque and output air lower temperature.
* In development.
Vacuum source for vacuum-servo braking systems. The pump is required low driven torque to conserve fuel. And it corresponds customer requirement by diverse driving methods and flexible installation.
Depending on the vehicle driving conditions, and by returning the exhaust gas with an appropriate amount to the intake side by the EGR valve, to lower the combustion temperature and reduce NOx. Using a motor or a solenoid, and by devising a valve shape, and has achieved a smaller and lighter.
EGR Valve (Motor driven)
EGR cooler bypass valve
To prevent over-cooling due to low-temperature EGR gas passing through the EGR cooler when starting the engine or at low temperatures, this switch valve bypasses the EGR cooler, reducing HC and CO exhaust. Uses a butterfly valve, and is not affected by pressure before or after the valve, so size and weight can be reduced.
Exhaust switch valve
An actuator that provides stepless control, for driving variable-capacity turbo-chargers, or as a replacement for conventional air cylinders. Uses a brushless motor for high reliability, and incorporates a spiral structure for compactness. Also has a fail-safe structure that returns to the safe position using a spring when the motor cutoff is damaged or other situations.
* In development.
Positive Crankcase Ventilation (PCV) Valve
Exhaust brake valve
This is an actuator for changing the nozzle angle in variable-capacity turbochargers. Motor-drive types capable of stepless control. Air-driven types can be stroked in steps by combining multiple air-intake ports. Multi-step stroke is only possible through air supply only, and a stroke sensor is not needed. Also uses a special piston structure with small diameter for compact size.
Two-stage Turbocharger Switch Valve
This valve switches between low and high pressure stages in turbochargers connected in series. When the engine is at low rotation speed, the valve is closes and the output of the low-pressure turbo feeds into the high-pressure turbo. When the engine is at high speed, enough air is being supplied to the engine, so the switch valve is opened, dividing the output of the low-pressure turbo over two paths: directly to the engine and through the high-pressure turbo, reducing the load on the high-pressure turbo.
* In development.
Various types of single cylinder for various applications such as engine stop, exhaust breaks, and for shifting.
Shift control booster
Shift control valve (emergency use)
An emergency air valve that enables mechanical operation when an electrical transmission shifter breaks down, avoiding complete breakdown on the road.
Cab tilting pumps
Cab tilting cylinders
An electromagnetic valve used to supply, maintain and release air in air springs under chassis frame of a vehicle. The valve is driven and controlled by computer to keep the height of a vehicle constant. This valve enables to adjust height of air suspension system equipped such as sight-seeing buses and trucks. Therefore to adjust the height of the vehicle helps passengers load and unload easily, or to adjust to the vehicle height against a loading platform, by operating switches.
A valve used to supply, maintain, and release air in air springs, to keep the height of a truck or cab constant. Compact, light-weight, and accommodating various vehicles by the lever shape.
For mechanical governor
For electronic governor
An electronic control system to prevent exceeding a speed limit. The limiter works to control heavy duty trucks speed under 90 km/h, even if the accelerate pedal is pressed.
Hydraulic pressure source and cylinders for opening and closing wing-doors on a truck platform. Compact and light-weight through integrated frame and tank, and reduced weight using aluminum. Incorporates forced wing closing function for emergencies, for increased reliability in unforeseen circumstances.
Automatic Greasing Equipment
Equipment that automatically applies a designated volume of grease to multiple locations. Grease fed from an air-driven pump is automatically applied through divider valves. The grease tank is a exchangeable cartridge type.
