Hydraulic coupling member with pressure-relieving poppet valve |
摘要 |
A poppet valve for a hydraulic coupling member has an internal, spring-loaded check valve (which may be a ball check valve) in fluid communication with a bleed passage. The check valve may be configured as a pressure-relief valve which bleeds off excess hydraulic fluid pressure within the coupling member to a preselected value. A poppet valve according to the invention may be used in female coupling members and/or male coupling members. Certain embodiments of the invention may be retrofitted to coupling members of the prior art. |
