Document Type and Number:
WIPO Patent Application WO/2019/208047
Kind Code:
A1
Abstract:
A cap (100) with an electromagnetic proportional valve comprises: a pilot cap (101) attached to a valve housing (1), the pilot cap (101) demarcating a pilot chamber (3); and an electromagnetic proportional valve (150) attached to the pilot cap (101), the electromagnetic proportional valve (150) controlling the pressure of a working fluid supplied to the pilot chamber (3). The pilot cap (101) has a supply port (111) through which the working fluid from a fluid pressure supply source (4) is supplied, a discharge port (112) that discharges the working fluid to a tank (5), a primary pressure passage (141) that guides the working fluid at a primary pressure from the supply port (111) to the electromagnetic proportional valve (150), a secondary pressure passage (142) that guides working fluid that has been depressurized to a secondary pressure by the electromagnetic proportional valve (150) to the pilot chamber (3), and a drain passage (143) that guides the working fluid discharged from the electromagnetic proportional valve (150) to the discharge port (112).
