FLUID CONTROL SYSTEM (DOHC TURBO MODELS)
CLUTCH
5. Fluid Control System (DOHC Turbo Models)
The clutch operating cylinder incorporates a temperature sensitive orifice unit which controls the
clutch engaging speed depending on the fluid temperature to ensure smooth standing starts irre-
spective of atmospheric temperatures.
A: CONSTRUCTION
The orifice unit consists of an orifice retainer, an orifice valve, and two springs that support the ori-
fice valve.
One of the springs is made of the shape memory alloy that prevents a delay in clutch response when
the weather is cold and the oil viscosity is high.

B: OPERATION
The No. 1 spring is made of a shape memory alloy that contracts and loses the tension when the
temperature is low.
When the temperature is high, the orifice valve is kept in a raised position by the No. 1 spring, so
the fluid passage is narrow. When the temperature drops, the No. 1 spring contracts, allowing the
orifice valve to be pushed down by the No. 2 spring. Now, the fluid passage in the orifice unit opens
wide.
