Claims Analysis

Total Claims: 24
Claim 1
Independent Claim 121 words
A miniature solenoid valve comprising a valve casing having a valve chest and a plurality of flow passages in communication with said valve chest formed therein; a valve body movably received in said valve chest for controlling the communication between the valve chest and said passages; and a solenoid provided adjacent to said casing for moving said valve body by means of a plunger, said valve being characterized in that said casing is formed with an opening in communication with said valve chest, said solenoid is removably received at one end of the casing in said opening and said valve casing and said solenoid are secured together by means of fixing means including fixing pins passing through the casing and solenoid.
Claim 2
Dependent Claim 121 words
A miniature solenoid valve comprising a valve casing having a valve chest and a plurality of flow passages in communication with said valve chest formed therein; a valve body movably received in said valve chest for controlling the communication between the valve chest and said passages; and a solenoid provided adjacent to said casing for moving said valve body by means of a plunger, said valve being characterized in that said casing is formed with an opening in communication with said valve chest, said solenoid is removably received at one end of the casing in said opening and said valve casing and said solenoid are secured together by means of fixing means including fixing pins passing through the casing and solenoid.
Claim 3
Dependent Claim 49 words
