Abstract
Official abstract text for this publication.
A control valve device includes a valve main body formed to have an actuator port connected to an actuator, a communication passage formed in the valve main body and configured to allow the actuator port to communicate with a drain port, and an on/off valve provided between the communication passage and the drain port, and the on/off valve includes a seat member assembled to the valve main body, an orifice provided in the seat member, and a poppet member configured to open and close a seat portion of the seat member.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control valve device, comprising: a valve main body formed to have an actuator port connected to an actuator; a communication passage formed in the valve main body, and being configured to allow the actuator port to communicate with a drain port; and an on/off valve provided between the communication passage and the drain port, wherein the on/off valve comprises: a seat member assembled to the valve main body; an orifice provided in the seat member; a poppet member configured to open and close a seat portion of the seat member, a valve body configured to hold the poppet member in a movable manner; a step portion formed in the valve body; and an annular projection formed in the poppet member, the annular projection and the step portion forming a stopper mechanism. 2. The control valve device according to claim 1 , wherein the seat member is sandwiched between the valve body and the valve main body. 3. The control valve device according to claim 1 , wherein the on/off valve further comprises a plug screwed to the valve body, the plug being configured to press the poppet member in a valve closing direction, and the poppet member abuts against the plug when the on/off valve is closed. 4. The control valve device according to claim 1 , wherein the stopper mechanism is configured to prevent the poppet member from coming out from the valve body and from causing a working fluid to flow out from the valve body to an outside. 5. The control valve device according to claim 1 , wherein the step portion has an inner dimension smaller than an outer dimension of the annular projection.
