ABSTRACT:
Described herein is an improved valve arrangement for use in connecting reservoirs containing photographic processing solutions with photographic processing apparatus. The valve arrangement comprises a valve (20) and a probe (10, 18). The valve (20) comprises a body portion (22) secured to the reservoir. A guide block (30) is fixed to the body portion (22) and carries a cap portion (32, 34, 36) defining a chamber (38) therebetween. The guide block (30) houses a plunger (42, 50, 66) in a chamber (58), the plunger (42, 50, 66) being biased by a spring (46) to seal against an opening (60) in the body portion (22). The probe (10, 18) is used to engage the plunger (42, 50, 66) and push it away from the body portion (22) to provide fluid communication between the reservoir and the processing apparatus.
