The invention relates to a coolant compressor comprising an electric drive unit, a cylinder housing (1), a crankshaft (3) which can be driven by the electric drive unit, and a piston (2) that can be driven by the crankshaft (3) and is guided in a working volume of the cylinder housing (1) for cyclically compressing a coolant which can be conveyed via a suction valve into the working volume, said suction valve comprising a suction opening (7) and a valve closure element (8), preferably a valve spring, which closes the suction opening (7) in cycles. The aim of the invention is to ensure a continuous opening movement of the suction valve during the suction cycle. According to the invention, this is achieved by providing an actuation device (14; 15, 23) which is designed to open the valve closure element (8) in cycles.

A materials handling vehicle including a load handling assembly having a mast assembly, and a fork carriage assembly including a fork support and at least one fork assembly, the at least one fork assembly including a first fork member, which is fixed to the fork support, and a second fork member. The vehicle includes a tilt assembly that tilts the fork support relative to the mast assembly such that a central axis of the at least one fork assembly is positionable in a plurality of different positions relative to a horizontal direction. The vehicle includes a fork extension/retraction assembly that moves the second fork member relative to the first fork member in a first direction that is parallel to the central axis such that the fork extension/retraction assembly selectively moves the second fork member toward or away from the fork support in the first direction.

A notch 41, which is formed on a land 31 that, in a main spool 30, blocks a reach-in side actuator port A from communicating with a second passage T, comprises a first notch and a second notch. The first notch comprises a first region that has a semi-circular shape in the plan view and in which the area of an opening between a valve body 40 and the land 31 becomes gradually larger, and a second region that is connected to the first region and in which the area of an opening between the valve body 40 and the land 31 is constant, and the second notch comprises a third region that has a semi-circular shape in the plan view and in which the area of the opening between the valve body 40 and the land 31 gradually becomes larger, and a fourth region that is connected to the third region and in which the area of the opening between the valve body 40 and the land 31 is constant.

Distance measurements are performed by a fork pocket detection sensor at a position at which the fork pocket detection sensor faces one of fork pockets and at a position at which the fork pocket detection sensor faces the central position in the horizontal direction between the fork pockets on a pallet side face, and information obtained by combining pieces of distance-measurement information acquired by the distance measurements is compared with information of predefined shapes of the fork pockets, so as to specify the positions of the fork pockets. Hereby, it is possible to accurately detect the positions of the fork pockets without causing a decrease of conveyance efficiency.
