BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a swash plate type compressor, and more particularly, to a crankcase refrigerant discharge device of a swash plate type compressor that moves refrigerant introduced into a crank chamber of a swash plate type compressor into a suction chamber.

Generally, an automobile has an air conditioner for cooling and heating the room. Such an air conditioner includes a compressor that compresses gaseous refrigerant of low temperature and pressure drawn from an evaporator into gaseous refrigerant of high temperature and high pressure and sends it to a condenser in the structure of a cooling system.

BACKGROUND ART [0002] Compressors that serve to compress refrigerant in a vehicle cooling system have been developed in various forms. Such a compressor includes a reciprocating type in which compression is performed while a refrigerant is compressed and a rotary type in which compression is performed while rotating. In the reciprocating type, there are a crank type in which the driving force of the drive source is transmitted to a plurality of pistons by using a crank, a swash plate type in which the swash plate is transmitted by a swash plate installed shaft, a wobble plate type in which a wobble plate is used, There are vane rotary type, scroll type using revolving scroll and fixed scroll.

When the refrigerant inflow amount from the discharge chamber 2 to the crank chamber 1 is increased, the pressure of the crank chamber 1 is increased, and the pressure of the swash plate 6 is increased. The inclination degree is reduced and the compression capacity is reduced. The high-pressure refrigerant in the discharge chamber 2 is moved to the crank chamber 1 in order to turn off the air conditioner or to minimize the swash plate angle during variable operation.

On the other hand, when the vehicle is left unattended for long time, the liquid refrigerant is introduced into the compressor. A cylinder fluid passage (11) is formed at one side of the cylinder (4) to move the liquid refrigerant in the crank chamber (1) to the suction chamber (3). The refrigerant in the crank chamber 1 is moved to the suction chamber 3 via the cylinder fluid passage 11 at the beginning of operation of the air conditioner.

Here, if the diameter of the cylinder fluid passage 11 is reduced, the discharge time of the refrigerant becomes longer and the operation time is delayed. However, if the diameter of the cylinder channel 11 is increased so that the coolant can be easily discharged, the discharge time of the coolant is shortened, so that the delay operation is improved but the control performance is deteriorated.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5, a crankcase coolant discharge apparatus of a swash plate compressor according to an embodiment of the present invention includes a discharge passage 10 for communicating a crank chamber 1 and a discharge chamber 2, A discharge passage 20 for discharging the refrigerant of the crank chamber 1 to the suction chamber 3 and a valve assembly 20 for opening and closing the discharge passage 20 so that the refrigerant of the crank chamber 1 can be introduced into the suction chamber 3 30).

The discharge passage 10 includes a cylinder passage 4 and a cylinder passage 11 communicating with the crank chamber 1 and a rear head passage 12 provided in the rear head 8.

The rear head flow path 12 is formed continuously with the cylinder flow path 11 so that the refrigerant in the discharge chamber 2 can move to the crank chamber 1. [ The refrigerant in the discharge chamber 2 flows into the crank chamber 1 through the discharge flow passage 10 so that the swash plate angle can be controlled by the refrigerant pressure in the discharge chamber 2. [

The rear head flow path 12 may be formed in one of the suction chamber 3 formed in the rear head 8 and the inner side wall of the discharge chamber 2. 2, the rear head flow path 12 is formed so as to protrude into the suction chamber 3. As shown in Fig.

3 to 4, the discharge passage 20 is formed by branching to one side of the discharge passage 10 and connected to the suction chamber 3. [ Therefore, the refrigerant flowing into the discharge passage 10 can be introduced into the suction chamber 3 through the discharge passage 20.

The valve assembly 30 includes an opening and closing valve 31 for opening and closing the discharge passage 20, a restoring means for moving the opening and closing valve 31 so that the opening and closing valve 31 opens the discharge passage 20, And a valve body (35) slidably accommodating the valve body (35).

The valve body 35 is fixedly coupled to the discharge passage 10 and has a slide hole 36 for slidably receiving the opening and closing valve 31.

The opening and closing valve 31 is slidably engaged with the slide hole 36 of the valve body 35 and closes the discharge passage 20 by the refrigerant pressure flowing into the discharge passage 10 from the discharge chamber 2.

The valve body 35 is formed in a cylindrical shape having a slide hole 36 and has refrigerant outlets 37 formed at both ends thereof and a discharge port 38 is formed in an inner wall of the slide hole 36.

The refrigerant on the discharge passage 10 can pass through the slide hole 36 through the refrigerant inlet / outlet 37. That is, the refrigerant flowing into the discharge passage 10 from the discharge chamber 2 can be moved to the crank chamber 1 through the refrigerant inlet / outlet port 37 and the slide hole 36.

The opening and closing valve 31 is provided at one side thereof with a refrigerant through hole 32 for communicating the discharge passage 10 and the discharge chamber 2 and is provided with a pressure space having a larger inner diameter than the refrigerant through hole 32 toward the discharge chamber 2. [ (Not shown). The opening / closing valve 31 has a refrigerant through-hole 32 formed at one end thereof and a pressure space portion 33 formed therein to form a generally cylindrical shape.

The refrigerant through hole 32 discharges the refrigerant flowing through the refrigerant outlet port 37 and the pressure space portion 33 of the valve body 35 from the discharge chamber 2 to the slide hole 36 of the valve body 35 . 4, the diameter d 1 of the pressure space portion 33 is formed to be larger than the diameter d 2 of the refrigerant through-hole 32, and at the same time, the refrigerant outlet 37 of the valve body 35, The diameter d 3 of the refrigerant flow path 32 is formed to be larger than the diameter d 2 of the refrigerant through-hole 32 of the opening and closing valve 31. Therefore, the refrigerant moving from the discharge chamber 2 toward the crank chamber 1 presses the inner wall of the pressure space portion 33, whereby the opening / closing valve 31 can overcome the restoring force of the restoration means and the crank chamber 1 .

The restoring means is an elastic member 34 elastically supporting the opening and closing valve 31. The opening and closing valve 31 opens the discharge passage 20 when the refrigerant does not flow into the discharge passage 10 from the discharge chamber 2. [ .

The discharge port 38 is formed to communicate with the discharge passage 20 so that the refrigerant introduced into the slide hole 36 of the valve body 35 can be introduced into the suction chamber 3.

The operation state of the valve assembly 30 will be described in detail with reference to Figs.

4 shows the operating state of the valve assembly 30 when the refrigerant moves from the discharge chamber 2 to the crank chamber 1 and FIG. 5 shows the operation state of the discharge chamber 2 and the suction chamber 3 shows the operating state when the refrigerant moves.

The opening / closing valve 31 maintains the state in which the discharge port 38 is opened by the elastic member 34 as long as external pressure by the refrigerant does not act.

4, when the refrigerant is discharged from the discharge chamber 2 to the discharge passage 10 during the operation of the compressor or during the variable operation thereof, the refrigerant is first introduced into the valve body 35 through the refrigerant inlet / The refrigerant is moved to the pressure space portion 33 of the pressure space portion 31 and the refrigerant pressure is applied to the inner side wall of the pressure space portion 33 so that the opening and closing valve 31 is moved toward the crankcase 1. The opening and closing valve 31 moves toward the crank chamber 1 and closes the discharge port 38 of the valve body 35 to block the refrigerant from flowing into the suction chamber 3.

The refrigerant in the pressure space portion 33 moves to the slide hole 36 of the valve body 35 through the refrigerant through-hole 32 while pushing the on-off valve 31, To the crank chamber 1.

5, when the refrigerant does not flow into the discharge passage 10 from the discharge chamber 2, the opening / closing valve 31 is restored to its original position by the restoring force of the elastic member 34, 38 are opened. At this time, when the refrigerant flows into the discharge passage 10 from the crank chamber 1, the refrigerant flows into the discharge passage 20 through the discharge opening 38 into the suction chamber 3.

When the discharge passage 20 is selectively opened and closed by the open / close valve 31 in accordance with the discharge pressure of the refrigerant discharged from the discharge chamber 2 to the crank chamber 1, the refrigerant flow for control of the swash plate angle and the operation The refrigerant discharge flow path of the initial crank chamber 1 can be independently ensured. Therefore, the diameter of the discharge passage 10 can be increased regardless of the control of the swash plate angle, thereby shortening the time for reaching the cooling setting temperature by advancing the compression start point of the initial operating refrigerant.

The refrigerant can be discharged from the crank chamber 1 to the suction chamber 3 at the beginning of the operation after the air conditioner is left for a long time and the refrigerant in the crank chamber 1 is introduced into the suction chamber 3 So that only the refrigerant in the discharge chamber 2 can be moved to the crank chamber 1.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious that the modification or the modification is possible by the person.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
