The disclosure provides a pressure control device that improves the workability in assembling a body and a filter unit. The pressure control device includes a body and a filter unit. The body has a flow path that includes a groove and a widened part. The widened part is connected to the groove, extends to a bottom of the groove, and has a width larger than a width of the groove. The filter unit is housed along a depth direction of the widened part to capture foreign matter mixed in a fluid that passes through the flow path. The filter unit includes a cylindrical frame and a flat plate-shaped filter member, wherein the frame includes a through hole part that penetrates in a direction orthogonal to a central axis, and the filter member is disposed to block the through hole part.

The oil content of at least two kinematic modules (1) in different axes of the industrial robot is connected by the oil line (2) to the closed circuit of the oil between interconnected kinematic modules (1). In preferred arrangement, the system includes the pump (3) engaged in pushing the oil in the upper-mounted kinematic module (1) and also the filtration device (4) for filtering the oil in the circulating circuit or in a separate circuit with the oil tank (9). The system may also include at least one diagnostic element (5), for example an oil temperature sensor or an oil pressure sensor or an oil pollution sensor connected to the evaluation unit (6). The evaluation unit (6) can be interconnected with the industrial robot control system, whereby the oil economy is controlled and planned depending on the actual load of the individual kinematic modules (1). By this arrangement, you can achieve the condition in which the oil from the kinematic module (1) circulates in shared circulation with the oil from another kinematic module (1), whereas the oil gets purified through the filter device (4) by using the pump (3).

The present disclosure is related to a transmission for a powered vehicle. The transmission includes a housing defining an interior of the transmission and a fluid supply portion disposed in the housing. The fluid supply portion is configured to supply fluid throughout the transmission. The transmission also includes a first fluid circuit disposed within the housing and defining a first fluid path in fluid communication with the fluid supply portion. A second fluid circuit fluidly defines a second fluid path in fluid communication with the fluid supply portion. The transmission further includes a coupling mechanism for fluidly coupling the first fluid circuit and second fluid circuit, wherein the second fluid circuit is disposed outside the housing of the transmission.

There is provided a control device for a vehicle oil supply device that includes a mechanical oil pump configured to be rotatable forward and in reverse, an electric oil pump configured to suction oil stored in an oil storage portion that is common to the mechanical oil pump and the electric oil pump, a first filtering member provided to a first strainer of the mechanical oil pump, and a second filtering member provided to second strainer of the electric oil pump.
