The present invention relates to a compressor test machine, and more particularly to a variable displacement compressor functional test machine including a mechanism for holding and testing various kinds of variable displacement compressors and for effectively testing the variable displacement compressors.
Various kinds of typical variable displacement compressors have been developed and provided for being used in various vehicles. For example, U.S. Pat. No. 7,381,031B2 to Kawaguchi et al., U.S. Pat. No. 7,452,192B2 to Hirota, U.S. Pat. No. 7,530,797B2 to Ito et al., and U.S. Pat. No. 9,863,411B2 to Saeki et al. discloses several of the typical variable displacement compressors each of which comprise a pulley of different or various diameters, such as 100 mm, 110 mm, 115 mm, 120 mm, 130 mm, 140 mm etc., and of different or various troughs or grooves, such as four grooves, five grooves, six grooves, eight grooves, ten grooves, twelve grooves etc., and for the typical variable displacement compressors, various kinds of typical test machines are required to be developed and provided for testing particular compressors, but may not be used for testing different compressors.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional variable displacement compressor test machines.
The primary objective of the present invention is to provide a variable displacement compressor functional test machine including a mechanism for holding and testing various kinds of variable displacement compressors and for effectively testing the variable displacement compressors.
In accordance with one aspect of the invention, there is provided a functional test machine for a variable displacement compressor comprising a stand, a chuck device supported on the stand, the variable displacement compressor being supported on the stand with said chuck device, a table supported on the stand, and the table including a control panel, a crankcase pressure (Pc) gauge, a discharge pressure (Pd) gauge, and a suction pressure (Ps) gauge supported on the control panel of the table and connected to the compressor, and a control valve device including a tubular member, and including a passage formed in the tubular member and coupled to the discharge pressure (Pd) gauge for receiving an air from the discharge pressure (Pd) gauge, and a valve member disposed in the tubular member and engaged into the passage of the tubular member for controlling an air flowing through the passage of the tubular member.
The chuck device includes three claws for holding the compressor. The compressor includes a pulley engaged with the claws.
The compressor includes a clutch and coil coupled to the control panel. The compressor includes a control valve coupled to the control panel.
Further objectives and advantages of the present invention will become apparent from a careful reading of the detailed description provided hereinbelow, with appropriate reference to the accompanying drawings.
Referring to the drawings, and initially to
As shown in
As shown in
Accordingly, the variable displacement compressor functional test machine in accordance with the present invention includes a mechanism for holding and testing various kinds of variable displacement compressors and for effectively testing the variable displacement compressors.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
