Abstract

PURPOSE:To improve reliability by utilizing reciprocal sliding motion of gate valve to pressurize lubricant and feed to the delivery pump side of gate valve thereby pressing the gate valve to uniformly contact against the suction hole side wall thus preventing shifted abrasion of gate valve. CONSTITUTION:When a gate valve 20 will approach to such position as the pressure in cylinder chamber 3 will increase to bring the load A due to gas pressure to the maximum level as a roller 4 rotates, an oil flow-in port 28 communicating between a pump chamber 26 and oil tank (not shown) is closed by said valve 20 to pressurize lubricant in the pump chamber 26 to feed through a communication hole 29 to the suction hole 12 of said valve 20 thus to apply load D for pushing the gate valve 20. Consequently the load D will prevail over the concentrated load to be produced conventionally by gas pressure A, to contact the gate valve 20 uniformly against the suction hole side wall of gate valve groove 25 resulting in prevention of burning due to shifted abrasion and improvement of reliability.
