摘要： A laser machining apparatus comprises a nozzle for ejecting a jet liquid to a workpiece and a liquid supply unit for supplying the jet liquid to the nozzle, while a laser beam is introduced into a jet liquid column ejected from the nozzle. The laser machining apparatus further comprises a laminar flow forming channel for supplying the jet liquid to the nozzle in a laminar state. The laminar flow forming channel includes a distribution channel formed by a cavity for annually distributing the jet liquid, which is supplied from the liquid supply unit, around an axis of the nozzle, an interconnecting channel disposed to be communicated with the distribution channel at the downstream side thereof in an axial direction of the nozzle and formed by an annular cavity around the axis of the nozzle to provide a narrower flow passage than the distribution channel, and a liquid reservoir chamber adjacently disposed upstream of the nozzle in the axial direction thereof and storing the jet liquid to be supplied to the nozzle. The liquid reservoir chamber has an outer peripheral edge being communicated with the interconnecting channel over an entire circumference of the annular shape thereof.

摘要： A high pressure hydraulic pump apparatus constituting a two-stage pressurizing hydraulic booster combining a pair of plunger pumps. The first and second pumps are driven into a push-pull synchronous operation at the equal stroke with each other. The per-stroke displacement of the first pump is greater than that of the second pump. The first pump draws by self-suction the liquid from a reservoir while the second pump is on the pressurizing and delivery stroke. When the first pump is on the delivery stroke, the liquid pressurized to a certain intermediate pressure by the first pump is sucked into the second pump. During the next reverse stroke the second pump further pressurizes and discharges the liquid while the first pump effects the suction stroke. At the final pressurization by the second pump, the driving stroke length of the pump is controlled to a limited value which provides a minimum delivery flow required for the interior of a load vessel to attain a target pressure in accordance with the compressibility of the liquid and the detection of a load pressure.

摘要： A liquid pressuring device comprises a reciprocating pump (1), pressure sensor (23) and pressure control unit (25) which is adapted to control the motion of the plungers (5A, 5B) so as to make an actual delivery pressure value reach a predetermined threshold and, after reaching the threshold, control the actual delivery pressure value so as to determine an optimum feed rate, and thereafter maintain the feed rate of the plungers constant at the optimum feed rate. The pressure control means (25) may include a proportional control element for performing, after the actual delivery pressure value has reached the threshold, the proportional control of the actual delivery pressure value during a time until the plungers (5A, 5B) first reach the forward stroke end thereof.
