Lip Seal

Lip Seal

This lip seal is a dedicated product that seals the rotating shaft of a compressor for car air-conditioning equipment. It prevents leakage of Freon gas and contributes to the prevention of global warming. The product enjoys a high market share, being used in various vehicles from small cars to large trucks all over the world.

Control Valve

Control Valve

This valve controls the inner pressure of an operating air-conditioning compressor and thereby reduces its rotational and engine loads, and improves fuel efficiency. The product is mounted on cars all over the world.

Mechanical Seal

Mechanical Seal

This mechanical seal is used to prevent leakage of coolant from rotating shaft of a cooling water pump that reduces the temperature of engine and electrical equipment. The seal has been produced in large quantity since 1957 and widely used in various vehicles from small cars to large trucks all over the world.

Carbon Bearing

Carbon Bearing

This submerged bearing is used in a cooling water pump that reduces the temperature of engine and electrical equipment. It is made of a carbon material of mechanical seal that has a long history of proven performance in coolant water applications, with high durability and resistance to heat and wear.

Metal Diaphragm Damper

Metal Diaphragm Damper

The pulsation (undulation and vibration of liquid) generated in a high-pressure fuel pump reverberates and creates noise in fuel pipe. This damper absorbs pulsation, reduces noise, and enables smooth flow of fuel.

Canister Purge Valve

Canister Purge Valve

To prevent leakage and pollution of the air, the fuel evaporated in a fuel tank should be sucked and burned in the engine. This solenoid valve controls the amount of fuel vapor sucked from a fuel tank into an engine.

Fuel Tank Isolation Valve (FTIV)

Fuel Tank Isolation Valve (FTIV)

This hybrid car-dedicated valve has been specially developed to comply with strict environmental regulations in the United States. The valve completely prevents fuel vapor from leaking from a fuel tank and eliminates air pollution.

Wastegate Actuator

Wastegate Actuator

This is an actuator of a wastegate that controls the flow rate of exhaust gases to regulate the maximum boost pressure in a turbocharger system. With its unique diaphragm structure made of thin rubber sheet, the product accurately detects boost pressure, actuates the wastegate, and protects the engine from damage caused by excessive boost pressure.

Variable Geometry Turbo Actuator

Variable Geometry Turbo Actuator

This is an actuator to control the angle of the vane nozzle (impeller) in a variable turbocharger. Appropriately controlling the angle of the vane nozzle enables you to achieve optimum turbo charging anytime, thereby providing smooth and powerful driving in a wide speed range from low to high.

Ejector

Ejector

This is a product used in turbocharged cars, which have become increasingly common in recent years. To prevent leakage and pollution of the air by gasoline vapor generated in a fuel tank, this valve helps to suck such vapor into the engine for combustion.

Check Valve

Check Valve

This check valve stops and controls fluid flow. It is used to prevent the back flow of turbo boost pressure through the process of sucking and burning of gasoline vapor generated in the fuel tanks of turbocharged cars, which have become increasingly common in recent years.

Metal Seal ECOCS®

Metal Seal ECOCS®

Metal seals are used in severe environments, such as high temperature and high pressure, in which normal rubber packing cannot endure. The unique C-shaped cross-sectional structure prevents the leakage of liquid and gas at high pressure.

Reed Valve for EGR System

Reed Valve for EGR System

This is a type of check valve to create a smooth EGR gas flow in the EGR system that reduces hazardous gas (Nox) in a diesel engine.

AT/CVT Solenoid Valve

AT/CVT Solenoid Valve

This valve is incorporated into an automatic transmission to switch the hydraulic flow according to vehicle speed and load, select the optimum transmission gear, and thereby contribute to lower fuel consumption.

Shock Absorber Solenoid Valve

Shock Absorber Solenoid Valve

This solenoid valve controls the hydraulic pressure in a shock absorber and adjusts the hardness (damping force control) of the absorber to achieve both ride quality and sportive driving pleasure. (Semi-active suspension system.)

Fuel Cell Solenoid Valve

Fuel Cell Solenoid Valve

This valve regulates the pressure of hydrogen gas supplied to the fuel cell. Taking advantage of the accumulated know-how in solenoid valves and metal bellows, it achieves excellent control performance (high responsibility). The design eliminates leakage and sliding parts by employing metal bellows for inner movable parts, thus allowing a resistant structure to contamination.

Bellows Products

Bellows Products

These bellows are produced by processing a thin metal pipe. With the advantage of a springy nature and high durability to pressure, they are used in various places such as the reciprocating parts of a fuel pump. In addition, they are widely used in many applications including the internal parts of the pressure sensor in a solenoid valve and accumulator.
