Title: Hydraulic negative pressure converter for automatic transmission
Inventor: HOSHINO NARIYUKI
IPC: B60W10/101
Filed: 1984-12-28
Abstract: PURPOSE:To enable a transmission to automatically change speed immediately after starting by the atmospheric pressure acting on a vacuum diaphragm immediately after starting at low temperature to provide high throttle pressure and line pressure. CONSTITUTION:Current is supplied to a solenoid 54 only before starting immediately after an engine is started at low temperature. When current is supplied to the solenoid 54, a negative pressure pipe path 60 is released to the atmospheric pressure which acts on a vacuum diaphragm 66. Thus, the vacuum diaphragm 66 exerts the largest force to a rod 74 and thereby hydraulic pressure in a port 76 has the highest value. Thus, in spite of high viscosity of oil, an automatic transmission can be set immediately to the transmissible condition.
