摘要： A hydraulic piston pump motor in which water is used as a working fluid includes an axial directional passage opened on an end surface of one end of a shaft that couples to a cylinder block and drilled open along a shaft center of the shaft; a first radial directional passage drilled open along a radial direction of the shaft from the axial directional passage and configured to guide working fluid into a casing; a second radial directional passage drilled open from the axial directional passage along the radial direction of the shaft at a position closer to the one end of the shaft than the first radial directional passage; and an introduction passage communicating a passage, through which the higher pressure working fluid flows, among the supply passage and the discharge passage with the axial directional passage.

摘要： It includes a plurality of cylinders formed on the cylinder block; a piston slidably inserted into the cylinder; a case accommodating the cylinder block; and a valve plate formed by a core member and a resin layer coating the core member, the valve plate being interposed between the cylinder block and an end cover of the case. The valve plate has a first land portion formed by the resin layer, the first land portion being in sliding contact with the cylinder block; and an outer-side non-contact portion provided closer to an outer side in a radial direction than the first land portion, the outer-side non-contact portion being separated away from the cylinder block. At least a part of the outer-side non-contact portion is an exposed portion where the core member is exposed.

摘要： [Abstract] A production apparatus for a liquid containing gas bubbles according to an embodiment of the present invention includes a casing and a shearing mechanism unit. The casing includes an inlet, into which a liquid with a gas injected therein flows, and an outlet. The shearing mechanism unit is provided between the inlet and the outlet and applies shearing force to a liquid flowing to the outlet from the inlet. The shearing mechanism unit includes a rotor, a rotation applying unit, and a facing member. The rotor includes a rotary shaft and a tube portion having an outer peripheral portion including a first structure surface in which a plurality of recess portions is formed, and is rotatably disposed inside the casing. The rotation applying unit is provided in the rotary shaft and applies rotating force around the rotary shaft to the rotor. The facing member has an inner peripheral portion that faces the first structure surface via a predetermined clearance and is provided in an inner wall portion of the casing.
