摘要： A piston pump is provided comprising a cylinder with an inner cylinder wall. The piston pump comprises at least one working space including fluid intake and fluid outlet, a piston including a piston rod and a piston head. The piston head includes a lateral surface facing the cylinder wall, a front surface facing the working space, a rear surface and at least one piston head channel. Furthermore, the piston head's lateral surface is provided with a first projection and a second projection extending round the entire circumference of the lateral surface and in contact with the cylinder wall, thereby forming an annulus which is defined by the first projection, the second projection, the cylinder wall and possibly the cylinder head's lateral surface between the first and the second projections if the piston head is designed so that the projections are provided with an axial spacing between them. The projections are designed so that a pressurized liquid located in the annulus will substantially flow into the cylinder's working space.

摘要： A piston pump is provided comprising a cylinder with an inner cylinder wall and a working space. The piston pump includes a piston inside the cylinder and has a piston head with a first and second projections extending from its lateral surface to the cylinder wall. These first and second projections enclose a cavity between the piston head and the cylinder wall. The piston head also includes a channel for routing a flushing fluid to the cavity. The first and second projections are configured to promote flow of the flushing fluid out of the cavity and into the working space of the cylinder.
