摘要： The invention relates to the slide shoe arrangement of a radial piston type of machine. This type of machine has a housing with a rotatable shaft and a piston carrier mounted on the shaft. Pistons in the carrier have reciprocal and radial movement relative to the carrier and shoes attached to the pistons have sliding engagement with an annularly shaped, eccentrically adjustable, track which surrounds the carrier. The track has a spherical surface portion with a predetermined radius R1. The shoes have spherically shaped surface portions of radius R2 which engage the track, radii R2 being larger than radius R 2 to form tapered gap chambers between the spherical shoe surfaces and the spherical track surface. The shoe portions may have annularly shaped flanges contacting the track surface through the spherical shoe surfaces. The flanges are resiliently connected to the shoe portions. A modification involves providing passages in the shoe portions which connect the gap chambers with ball and socket connections between the pistons and the shoes.

摘要： The invention relates to a hydraulic planetary piston motor of the type having an externally serrated pinion gear which meshes with an internally serrated ring gear and has rotatable and orbital movement relative thereto. The unit has plate type distributor valving with fixed and moveable members and a piston, subject to control pressures on both sides thereof, for biasing the moveable valve member into sealing engagement with the fixed valve member. A change-over valve which may be pressure controllable functions to either cause biasing of the piston to effect the sealing mode or to relieve the biasing to cause a separation of the valve members to effect a short circuiting unloading thereof.
