IPC: F15B11/00
Filed: 1999-12-27
Abstract: PROBLEM TO BE SOLVED: To provide a warming structure for a hydraulic pilot controlled hydraulic circuit that can clear way at least either nonconformity of or demand for conventional warming, if not, a totally renewed warming structure. SOLUTION: This hydraulic pilot controlled hydraulic circuit includes a warming structure, such that pressured oil is delivered into pilot lines (13L, 13R) via a shut-off valve (16) to provide warmth to the both pilot lines (13L, 13R), when an operation lever 11 is in neutral position. This warming structure includes a directional control valve (1), which has communication lines (1fL, 1fR) at both ends of a spool (1b) when the spool (1b) is in the neutral position, such that a drain chamber (1e) of a valve body (1a) and pilot pressure chambers (1cL, 1cR) are made to communicate via the communication lines (1fL, 1fR).  The both communication lines (1fL, 1fR) are arranged and a communication passage area of one side (1fL or 1fR) of the communication lines is gradually increased in proportion to a sliding distance amount of the spool (1b), when the spool is moved from the neutral position to one side, while a communication passage area of other side (1fR or 1fL) of the communication lines is decreased gradually.
