Double sided pressure relief valve for hydraulic motor

摘要

The relief valve (16) has a valve housing (H) with a spool (28) which controls the second and third bores. An attachment nut (40) is formed as part of the fourth bore to allow the nut to be screwed onto the right hand side diameter of the valve housing. A sleeve (26) is inserted between the nut, and holds a spring (38) and the valve housing. A left hand side cap (24) on which the first bore is formed defines the second bore.
