Title:
FLUID CIRCUIT
Document Type and Number:
Japanese Patent JPS59164402
Kind Code:
A
Abstract:
PURPOSE:To easily increase a switching valve for an optional function without the need of remodeling a switching valve block for a standard function by connecting the switching valve for an optional function to a discharge path of a liquid pressure pump in parallel with the switching valve for the standard function. CONSTITUTION:A fluid circuit comprises a variable-capacity liquid pressure pump 2, a flow direction switching valve 4 for a standard function, a feathering valve 16, a by-pass pressure control valve 25 and a flow direction switching valve 30 for an optional function connected to a discharge path of the liquid pressure pump 2 in parallel with the switching valve 4. Therefore, addition of an optional function can be accomplished only by detaching an outside feathering pipeline 19 for a standard function and attaching an outside load pessure detecting pileline 40 for an optional funtion and an outside feathering pipeline 41 for an optional function. Thus, such addition can be performed simply and with good work efficiency.
