Abstract: A check valve (1) is described, the check valve (1) comprising a valve housing having a first port (2) and a second port (3) connected to a valve chamber (4), a valve seat (5) having a valve seat axis (6) and being arranged between the first port (2) and the valve chamber (4), and a valve element (7) movably arranged within the valve chamber (4) between the valve seat (5) and a stop face (8) opposite the valve seat (5), wherein the valve housing comprises a first part (9) having the first port (2) and a second part (10) having the second port (3) and being connected to the first part (9).
Such a check valve should have a simple design.
To this end the second port (3) opens into the stop face (8) by means of an array of holes (12), wherein the cross section area of the holes (12) is smaller than the smallest cross section area of the valve element (7).

Abstract: A method of manufacturing a pin (roller) holding ring for a gear mechanism in which external gears (5a, 5b) are meshed internally with an internal gear (20) comprising a pin (roller) holding ring (110) having semi-circular pin (roller) holding holes in the inner peripheral side and pins (rollers) (11) close-fitted rotatably in these pin holding holes, the method comprising the steps of drilling fully circular pin holding holes (113a) in a ring base material before the inner diameter DA of a pin holding ring base material (151) is machined to a finish diameter, and expansion-machining the inner diameter of the pin holding ring up to a finish diameter after the inner surfaces of the pin holding holes have been surface-finished by a roller burnishing machining so as to provide the pin holding ring having semi-circular pin holding holes, whereby the sliding rotation of the pins in the pin holding holes can be improved.

Abstract: A hydrostatic transmission (34, 35) including a variable displacement pump (56) including an input shaft (40) and a pump cylinder barrel rotatably coupled to the input shaft, the pump cylinder barrel having a plurality of cylinder chambers arranged in parallel with other and distributed about the input shaft axis of rotation. Each cylinder chamber has a reciprocating piston therein which bears against a pivotable swashplate, the displacement of the pump being varied in response to changes in the position of the swashplate. A gerotor motor (66) is attached to the pump and has an output shaft (128). The motor includes an engaged pair of inner (120) and outer (118) members, the outer member being eccentric relative to the inner member. The inner member is rotatably driven relative to the outer member by fluid received between the inner and outer members from the pump, the inner member being drivingly connected to the output shaft. A plurality of fluid conduits (58, 60) extend between the pump to the motor, through which the motor is in fluid communication with the pump.

Abstract: A method of controlling the shifting of a multiple-speed ratio fluid pressure operated motor (10) between a first speed ratio (FIG. 3) and a second speed ratio (FIG. 4), the motor including a gerotor gear set (21) defining a plurality of expanding (33E) and contracting (33C) fluid volume chambers. The motor includes a shift valve (61) operable, in a first condition, to achieve the first speed ratio, and in a second condition, to achieve the second speed ratio by interconnecting a plurality of said volume chambers as recirculating volume chambers (33R). The method comprises the step of shifting the shift valve between the first and second conditions in response to changes in a pilot pressure signal (71). The method includes providing a pressure control valve (75) in fluid communication with a source (73) of pressurized fluid, the pressure control valve (75) being operable to communicate the pilot pressure signal to the shift valve (61) in response to changes in an electrical command signal (113) between a first signal (113B) and a second signal (113C). When a shift to the second condition (FIG. 4) is commanded, the method changes the electrical command signal (113) from the first signal (113B) to the second signal (113C) over a first time period (T1). When a shift back to the first condition (FIG. 3) is commanded, the method changes the electrical command signal (113) from the second signal (113D) to the first signal (113E) over a second time period (T2), wherein T2 is greater than T1.
