Vehicle body position control system
First Claim
1. A vehicle body position control system, comprising:
- first and second actuator means operated by a pressurized air for generating vertical movement of said vehicle body;
air compressor means for supplying said pressurized air to said first and second acutator means;
air passage means interconnecting said compressor means and said first and second actuator means;
air dryer means, including a desiccating agent disposed therein, being positioned within said air passage means between said compressor and said first and second actuator means;
said air passage means having a first branch passage leading therefrom between said compressor means and said dryer means, said first branch communicating with the atmosphere;
first solenoid valve means positioned within said first branch passage;
second solenoid valve means in said air passage means between said dryer means and at least one of said first and second actuator means;
control means for controlling operation of said first and second solenoid valve means and said compressor meand, said control means including delay means for opening said second solenoid valve means with a delay of a predetermined time after opening said first solenoid valve means, to thereby release said pressurized air within said at least one of said first and seocnd actuator means into the atmosphere through said dryer means.

Abstract
A vehicle body position control system which includes a first and second actuator operated by a pressurized fluid for generating vertical movement of the body vehicle, a compressor for supplying the pressurized fluid to the first and second actuators, a fluid passage interconnecting the compressor and the actuators, a dryer having a desiccating agent therein and positioned within the fluid passage between the compressor and the actuators, a branch passage leading from the fluid passage between the compressor and the dryer, a first solenoid valve positioned within the branch passage, a control mechanism for controlling operation of the first solenoid valve and the compressor, and second and third solenoid valves in communication with the fluid passage between the dryer and the first and second actuators and operated respectively via the control mechanism after a predetermined time delay period subsequent to operation of the first solenoid valve, for thereby releasing pressurized fluid within the actuators to the atmosphere through the dryer.
