Abstract

PURPOSE:To reduce the starting torque of a compressor by constituting so that an air holding and feed/discharge valve in a car height adjusting body is closed and a valve opening/closing to the outside between this valve and the compressor is opened for a fixed time. CONSTITUTION:A car height sensor outputs car height signals SH, SL. Individual signals are applied to timer circuits 12, 13 respectively. In case of a high car height, a driver 19 is driven by an SHa signal through an OR gate 15 and drivers 20, 21 are driven through an OR gate 14 and an AND gate 18, thus a discharge valve 8 and cut valves 7a, 7b are opened. In case of a low car height, the cut valves 7a, 7b are closed and the discharge valve 8 is opened by an SLa signal to drive a compressor 6. Thereby, the cylinder pressure of the compressor 6 is lowered to near the atmospheric pressure to reduce its load. Accordingly, the starting torque of the compressor is reduced to allow smooth starting.

Description

[Detailed Description of the Invention] Ko7JJljl! 14 relates to a single adjustment device designed to reduce the field torque υ of a compressor that is self-heating.

The well-known "υ trace, #IIIk hook garage is to reduce the air pressure in the vehicle crystal adjustment spring (the air spring is inserted between the garage and the single shaft) &, moreover, the vehicle body. L/JMJ Zawo 1
I'm arrogant. When the four of us pick up the car now,
i'1m storage UJ air supply (connected to the valve port, cut 1 magnetic valve t-open, send air from the compressor to the tunshing control warehouse 7'
At the same time, when the garage is raised, the HO cut valve is closed, and when the garage is pulled up, the HO cut valve is opened and the air is filtered. After exhausting the air to the outside and reaching sr9r constant 1/J and cr, Cut 1 "The magnetic valve is closed and the control is performed to maintain the VJ position." By the way, when starting the compressor mentioned above, , due to the υ reaction between the VJ air pressure inside the combustor cylinder and the υ reaction, a large negative torque is generated in the combustor, and when starting +UJ, a considerably larger starting torque is required than during reverse operation. .

Because of the VJ, Tanabata also inevitably required VJ stuff, and the KL space with J■ was large, which led to the cost of MJt in '6. Use a lever to hold this subcommittee (I).In general/J compressors, avoid the Ajiroder structure, and when starting the compressor, in the J cylinder,
R Increase the atmospheric pressure and push the motor.” M MuJ
) A method of reducing the cost of Tanabata to make it smaller and cheaper.1j1 This method is widely used. The compressor that is used for the axle adjustment device is originally small! ! I! !
However, even if you try to make the Tanabata smaller by installing 11 needles, the unloader will still be small. Since the cost is the remaining Lido B, either the cost will increase due to the miniaturization of the 7-tor, or the increase in the gamma loader machine F4 (this will cancel out the cost increase, so there is not much benefit even in terms of cost. The subcommittee agreed.

L:L/J Bakumei, taking the above VJ's 1d approach, offers a vehicle weight TD11 adjustment device that achieves miniaturization (more space) and lower cost for the compressor drive sweater. In the forest,
When the conbrella length is 0.

Based on Kaidoketsu, I will explain Honkaaki's Iike example.

・Add the tjth draft, and when the compressor starts, open only the magnetic valve installed at the discharge port, - write down the time immediately, close the magnetic valve. In addition, by opening the 4-magnetic valve, it is possible to realize a compressor unloader M+7, which has the advantage of reducing the motor starting torque. I'm arrogant. ! ! In addition, since it is possible to carry out the small A%-YT of the start-up drive, it is possible to lower the Tanabata function and reduce the installation space as shown in Fig. 60. In addition, a further advantage can be obtained by locking the 7-tor υ lock at the time of starting the compressor: AJI.
