Abstract
Abstract A modulator valve control for an automatic transmission to provide an input which determines the shift point at which the transmission changes from one mode to another. The assembly includes a modulator valve having a plunger extending therefrom and into a housing. A motion transmitting remote control is included and comprises a guide means attached to the housing and a flexible motion transmitting core element movably supported by the guide means and connected to a flat leaf spring. The flat leaf spring interconnects the core element and the plunger of the modulator valve for actuating the modulator valve in response to motion of the core element.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
89 words
A transmission assembly comprising; a modulator valve, a motion transmitting remote control including guide means and a flexible motion transmitting core element movably supported by said guide means, and a flexible lever means extending in a cantilevered fashion from a support and engaging said valve, said core element being attached to said lever means for actuating said valve upon movement of said core element, said lever means including a flat spring, said spring engaging said valve at a position between said support and the attachment to said core element.
Claim 2
Dependent Claim
89 words
A transmission assembly comprising; a modulator valve, a motion transmitting remote control including guide means and a flexible motion transmitting core element movably supported by said guide means, and a flexible lever means extending in a cantilevered fashion from a support and engaging said valve, said core element being attached to said lever means for actuating said valve upon movement of said core element, said lever means including a flat spring, said spring engaging said valve at a position between said support and the attachment to said core element.
Claim 3
Dependent Claim
52 words
An assembly as set forth in claim 1 wherein said spring is moved from a neutral position in response to a tension force being applied to said core element and said spring returns to said neutral position when said tension force is removed from said core element to return said core element.
Claim 4
Dependent Claim
27 words
An assembly as set forth in claim 2 wherein said spring extends from said support to said valve and thereafter through a bend and in another direction.
Claim 5
Dependent Claim
15 words
An assembly as set forth in claim 3 wherein said bend is approximately 90* .
Claim 6
Dependent Claim
28 words
An assembly as set forth in claim 3 wherein said bend is such as to always maintain a force on said core element when in said neutral position.
Claim 7
Dependent Claim
32 words
An assembly as set forth in claim 3 including a housing, said support being disposed in said housing, said guide means being attached to said housing, said valve extending into said housing.
Claim 8
Dependent Claim
52 words
A transmission assembly comprising a modulator valve, a motion transmitting remote control including guide means and a flexible motion transmitting core element movably supported by said guide means, flat spring means operatively connected to said valve, said core element being connected directly to said spring for actuating said valve through said spring.
Claim 9
Dependent Claim
52 words
A transmission assembly comprising a modulator valve, a motion transmitting remote control including guide means and a flexible motion transmitting core element movably supported by said guide means, flat spring means operatively connected to said valve, said core element being connected directly to said spring for actuating said valve through said spring.
Claim 10
Dependent Claim
52 words
An assembly as set forth in claim 7 wherein said spring is moved from a neutral position in response to a tension force being applied to said core element and said spring returns to said neutral position when said tension force is received from said core element to return said core element.
