    摘要: A turbine-type underwater hydraulic motor includes a hermetically sealed chamber filled with oil, and bearings of rotating parts and a reduction gear unit are sealed in said sealed chamber. A part of the partitions isolating the sealed chamber from the exterior is comprised of a resilient member and thus the water pressure outside the motor and the oil pressures within the sealed chamber are balanced, thereby preventing the leakage of the oil and the entry of the water.

    摘要: A variable displacement swash plate compressor comprises a rotating shaft, a swash plate fitted on the rotating shaft to engage the rotating shaft slidably and to be variable in inclination relative to the rotating shaft, thereby rotating synchronously with the rotating shaft, a first spring for forcing the swash plate in the direction decreasing the inclination of the swash plate, a second spring for forcing the swash plate inclined to near the minimum inclination in the direction increasing the inclination of the swash plate, and a damper for countering the short period variation of the inclination of the swash plate inclined to near the minimum inclination.

    摘要: The present invention relates to a reciprocating pump in which a plunger is reciprocated by means of a crankshaft, a connecting rod and a crosshead. The reciprocating pump further includes cushioning means which is disposed between the crosshead and the plunger and capable of adjusting its cushioning force and absorbing the plunger stroke, whereby the delivery pressure is adjustable through adjustment of the cushioning force of the cushioning means and the delivery volume or rate is also adjustable through absorption of the plunger stroke by the cushioning means.

    摘要: Disclosed is a tube expander in which a mandrel itself is in the form of a short metal bar and the mandrel is fitted into a cage having loosely fitted therein a plurality of rollers adapted to perform a tube expanding function. The forward end of the mandrel includes a threaded portion formed in the outer surface thereof and engageable with a threaded guide disposed inside the forward end portion of the cage and adapted to be rotatable with the cage and slidable axially thereof, and the rear end of the mandrel is engaged with a mandrel drive which axially slidably rotates the mandrel. A suitable number of shanks may be added to the mandrel drive as occasions demand, whereby the desired tube expanding operation can be performed without the need to apply any propelling force to the mandrel drive but simply by externally applying a turning force to the mandrel drive or the shanks.
