Title: Variable capacity swash plate type compressor
Inventor: AN HYU NAM
IPC: F04B27/08
Filed: 1998-11-10
Abstract: PURPOSE: A variable capacity swash plate type compressor is provided to effectively prevent the torsion of a swash plate by a rotary screen by dispersing the suction force and the compressive reaction force through a hinge. CONSTITUTION: A swash plate(34) rotates with a certain inclination angle through a hinge as a drive shaft(24) revolves. The rotation of the swash plate is converted into the reciprocation of pistons(50) in each cylinder bore(14) through shoes(52). Refrigerant gas is introduced into each cylinder bore from a suction chamber(58) to be compressed by the reciprocation of the pistons. Then, the compressed refrigerant gas is discharged to a discharge chamber(60) from the cylinder bores. The amount of the refrigerant gas discharged to the discharge chamber is controlled by a pressure controller(72) for controlling the pressure of a crank chamber. The inclination angle of the swash plate increases so the compressive capacity of a compressor as to increase by extending the stroke length of the pistons if the load of an evaporator increases. However, the inclination angle of the swash plate decreases so the compressive capacity of the compressor as to be reduced if the load of the evaporator decreases.

A memory(814) stores current frame data and previous frame data. A basic searching unit(800) reads block data of a predetermined size of the current frame and search area data of the previous frame from the memory and outputs the matching criterion value of these data. A partial MAD storing unit(812) divides a search area into a block size, and stores and outputs an output value of the basic searching unit upon receipt of data in each divided search area and the block data, which is the value obtained by summing a previously stored value, in case of search at the lower level. A comparison unit(804) outputs an index of a corresponding searching point in the search area which is outputted from the partial MAD storing unit and has a minimum value by sequential comparison, wherein a searching is achieved at the lower level(104). An address generation unit(808) obtains a motion vector from the index when the searching is achieved at the lower level(104).
