OIL PRESSURE GENERATING DEVICE AND CROSSHEAD ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/182004
Kind Code:
A1
Abstract:
In an oil pressure generating device (200) of a crosshead engine, the tip is located on the outer part of the main member, and the base faces a pressure-boost chamber (216) inside the main member (202). The oil pressure generating device (200) has: plungers (210a, 210b) that slide in a direction intersecting the stroke direction of a piston; first pressing parts (236, 240) that are disposed apart from the main member in the sliding direction of the plungers, wherein the distance of separation from the main member is a first distance (La), and the pushing amount of the plungers into the pressure-boost chamber side is a first pushing amount; and second pressing parts (238), wherein the distance of separation from the main member is a second distance (Lb), and the pushing amount of the plungers into the pressure-boost chamber side is a second pushing amount that is greater than the first pushing amount. The oil pressure generating device (200) is provided with plunger pressing members (204a, 204b) that push the plungers to the pressure-boost chamber side in the process of the plungers moving from the first pressing parts to the second pressing parts.
