摘要： PURPOSE:To reduce the influence of the in-pipe resistance of a circuit by shortening a passage in which viscous substance such as grease etc. passes. CONSTITUTION:During the time when a discharge plunger 7 operates, all the passages which lead to a discharge-side main pipe from an inflow-side main pipe are shut-off at the position of the spool 6 of a pilot valve. In other words, communication between an inflow passage 13 and a through-hole 15 which communicates to a main passage is shut-off in the gap part of the spool 6, and a bypass passage 14 is shut-off by a check valve 5'. While, when the spool 6 operates after the discharge plunger 7 operates, the inflow passage 13 communicates to an introducing hole 15'. Therefore, viscous substance flows through a main passage 11, bypass passage 14, inflow passage 13, the gap part of the spool 6, introducing hole 15', and a main passage 11'.
摘要翻译：目的：通过缩短粘性物质如油脂等通过的通道来减少回路的管内阻力的影响。构成：在排出柱塞7动作的期间，从导阀的阀芯6的位置切断从流入侧主管通向排出侧主管的所有通路。换句话说，流入通道13和与主通道连通的通孔15之间的连通在阀芯6的间隙部分被切断，旁通通道14被止回阀5'切断，。另外，当排出柱塞7动作后，当阀芯6动作时，流入通路13与导入孔15'连通。因此，粘性物质流过主通道11，旁通通道14，流入通道13，阀芯6的间隙部分，引入孔15'和主通道11'。
