Thereby once fuel module 20 energising selector switch 76 is switched on, selector switch 76 is optionally transferred to so-called " spray gun " thereby position switches on the first eletromagnetic-operating device 170 on spray gun valve 130 by the first electric control line 174.Similarly, if selector switch 76 moves to so-called " tank " position, thus the second eletromagnetic-operating device 172 is switched on and is opened the pot valve 154 of above-mentioned eletromagnetic-operating by the second electric control line 176.Therefore, when selector switch 76 moves to so-called " spray gun " position, eletromagnetic-operating device 170 switches on to open spray gun valve 130, thereby and substantially simultaneously eletromagnetic-operating device 172 power-off close pot valve 154.On the contrary, when selector switch moves to so-called " tank " position, eletromagnetic-operating device 172 switches on to open pot valve 154, and substantially simultaneously eletromagnetic-operating device 170 power-off to close spray gun valve 130.By such setting, fuel module 20 can be used for discharging by the first fuel module discharge system the gaseous fuel (preferably rock gas) compressing and reaches the object of tank operation, or by the second fuel module discharge system, reaches the object of reservoir vessel postcombustion or other this application.
For the indication of whether selecting " spray gun " or " tank " pattern is provided to user, spray gun indicator feeder 214 is electrically connected mutually to supply power to spray gun tutorial light 80 from the first electric control line 174.Similarly, tank indicator feeder 212 is powered between the second electric control line 176 and tank tutorial light 82.
For the desired operation mode of the reservoir vessel 64 shown in spray gun assembly 16 or Fig. 2 for shown in Fig. 1, by starting the operation of fuel module 20 to carry out from the suitable interconnection of fuel module 20 description of simplified summary.Then fuel module 20 can interconnect by fast connecting joint 102 and gas fuel supply system 100, is mutually electrically connected subsequently by electric connection 202 with power supply 200.
When main power switch 74 moves to the position of " opening ", the eletromagnetic-operating device 226 of power supply indicator 78, selector switch 76, compressor 116, fan electromotor 230 and entrance is all switched on, thereby open, is communicated with and opens fuel module 20 with the fluid of gas fuel supply system 100.Selected according to which position of selector switch 76, suitable spray gun tutorial light 80 or tank tutorial light 82 are also switched on and light.
When main power switch 74 moves to the position of " opening ", and selector switch 76 is while being moved into the position of " spray gun " pattern, and spray gun valve 130 is opened, and pot valve 154 is closed simultaneously.This situation makes the gaseous fuel of compression be provided to spray gun assembly 16 by the first fuel module discharge system, and head pressure is selectively adjusted and is controlled by adjustable modulator 136 and its spray gun pressure adjusting color controls 86 simultaneously.As mentioned above, the adjusting of this head pressure can realize in predefined extreme value by safety valve 184 that preferably can manual tune in the first fuel module discharge system.
Similarly, when selector switch 76 moves to the position of " tank ", pot valve 154 is opened, and spray gun valve 130 cuts out substantially simultaneously, thereby the gaseous fuel of compression is substantially directly drained into reservoir vessel 64 or used the application of fuel for other by the second fuel module system of discharging.As mentioned above, the fuel module head pressure in arbitrary aforesaid operations pattern is finally by the selected predefined maximum compression machine head pressure setting value control of the adjustable pressure cut off equipment 180 of preferred manual.
On the contrary, when main power switch 74 moves to the position of " pass ", thereby whole fuel module 20 is closed in said modules power-off.About this point, it should be noted that due to not for compression rock gas internal storage device is provided, the rock gas of compression can be retained in fuel module 20.This feature has significantly increased the Security of fuel module 20 by substantially avoided the gathering of gaseous fuel of pressurization in the non-use period.
