This is a compressed air source for full air brakes or air over hydraulic brakes. It is adopted for medium to large trucks.
To meet diverse customer needs, we offer a comprehensive lineup covering small to large flow rates.

Mounting configurations can be designed to match vehicle specifications. Our proprietary head structure significantly improves compressed air cooling efficiency.
The split structure of the crankcase and liner, combined with aluminum construction, reduces vehicle weight.

Primarily adopted as the vacuum source for brake vacuum boosters in small trucks.

Various capacity settings are available to meet customer requirements, and exterior customization is possible according to installation conditions.

Furthermore, optimization of each internal structure contributes to high efficiency and low noise.

Primarily adopted as the vacuum source for brake vacuum boosters in small trucks.

Direct connection to the engine’s camshaft shaft reduces component count and enables stable vacuum generation.
Optimized internal structure contributes to low torque, high efficiency, and low noise.

This is a directional switching valve for exhaust gas in small truck engines.

By bypassing the EGR cooler, it prevents excessive cooling and effectively reduces HC and CO emissions during engine startup and low-temperature operation.

This valve returns blow-by gas leaking from the engine combustion chamber into the crankcase back to the intake side.

It helps prevent air pollution caused by blow-by gas and maintains proper pressure within the engine crankcase through its diaphragm structure.

This air cylinder adjusts the nozzle angle of a variable-capacity turbocharger to control boost pressure.

The air cylinder’s stroke can be adjusted in 8 stages, enabling optimization of the turbocharger’s boost pressure.

A single-acting air cylinder suitable for various applications.

This air cylinder returns to its initial position (minimum stroke length) when air is released, thanks to the spring inside the cylinder.

This air-powered power-assist product assists gear shifting operations in transmissions for medium-to-large trucks and buses.

By utilizing air pressure, it reduces the driver’s load during gear shifting.

This hydraulic pump is designed for cab tilt systems in large, medium, and small trucks.

By utilizing an electric motor and piston pump, it achieves both maximum pressure and compact design.
